Chart recorder DS 500 - Intelligent chart recorder for compressed air and gases Measurement - control - indication - alarm - recording - evaluation Advantages at a glance: • Clear layout: 7" colour screen with touch panel... • Versatile: 4, 8 or 12 sensor inputs. Up to 12 analog sensors or up to 40 digital sensors (Modbus RTU). • Suitable for industrial applications: Metal housing IP 65 or panel mounting... • Data available through world wide web: Net- work-compatible and remote transmission via webserver • Mathematical function: for internal calculations • Totalizer function: for analog signals • ...saves time and costs during installation • Simple: DS 500 provides the power supply for the sensors DS 500 - the intelligent chart recorder of the next generation Recording of the measured data, indication on a big colour screen, alerting, storage, not to mention remote read-out via webserver... this is all possible with DS 500. All measured values, measurement curves and threshold value exceedances are indicated. The curve progressions from the beginning of the measurement can be viewed by an easy slide of the finger. The big difference to ordinary paperless chart recorders reveals in the easy initiation and in the evaluation of the measured data. All sensors are identified directly and powered by DS 500. Everything is matched and tuned. Mathematical function for internal calculations, e.g. the typical figures of a compressed air system: • • • costs in $ per generated CFM air kWh/CF generated air consumption of single lines including summation Totalizer function for analog signals (e.g. 0/4…20 mA, 0…10 V). In case of third-party sensors which e.g. only give a 4...20 mA signal for the actual flow in cfm, a total counter reading in m³ can be generated by means of the Totalizer function. No time consuming studying of the instruction manual... this saves time. Internal voltage supply of all sensors, no wiring of external mains units ... this saves additional costs. 12 www.cs-instruments.com/us

Chart recorder DS 500 mobile - intelligent mobile chart recorder The intelligent chart recorder of the future - energy analysis according to DIN EN 50001 If we talk about operating costs in compressed air systems, we are actually talking about the energy costs, because the electricity costs make up about 70-80% of the total cost of a compressed air system. Depending on the size of the system, this means considerable operating costs. Even in smaller systems, this may quickly add up to 12,000 to 25,000 $ per year. This is an amount which can be considerably reduced - even in case of well operated and maintained plants. Does this also apply to your compressed air system? Which are your actual costs per generated cubic feet air? Which energy is gained due to the waste heat recovery? What is the total performance balance of your plant? How high are the differential pressures of single filters, how high is the humidity (pressure dew point), how much compressed air is used? By means of the new intelligent chart recorder DS 500 mobile and the suitable sensors and meters all these questions can be answered easily. For example by means of a long-term measurement over 7 days, data recording and evaluation on the PC. 12 sensor inputs Including voltage supply for all sensors Touch screen USB stick Ethernet connection 26 www.cs-instruments.com/us

Chart recorder Analysis of specific power: By measuring power consumption and delivery volume simultaneously, it is possible to calculate the specific power of the compressor. The specific power is calculated using the ratio of the required energy consumption in kWh to the volume of air in m3 output during the same period. Specific power = kWh m³ The specific performance indicator of the compressor supplies information about the compressor’s characteristics. The ‘traffic light’ graphic below can be used as an aid to assessment: 6 7.2 8.4 9.6 10.8 12 13.2 14.4 kW m³/min kWh m³ 0.1 0.12 0.14 0.16 0.18 0.2 0.22 0.24 A typical specific power requirement for an oil-injected compressor might look something like this: Delivery volume: 43.7 Nm³/min (according to ISO 1217 based on 20° C + 1 bar) Total power consumption: 272.7 kW Specific power requirement = 272.7 kW/43.7 m3/min = 6.24 kW/m3/min = 0.104 kWh/m3 DS 500 PM MOBILE TECHNICAL DATA Case dimensions: 14.1 x 10.6 x 5.9 Inch Weight: Material: Sensor inputs: 9.9 lbs Diecast, front foil polyester, ABS 3/7/11 sensor inputs for analog and digital sensors; freely allocatable.

Chart recorder Energy analysis - consumption measurement - leakage calculation DS 500 mobile - Energy analysis according to DIN EN 50001 If we talk about operating costs in compressed air systems, we are actually talking about the energy costs, because the elec- tricity costs make up about 70-80% of the total cost of a com- pressed air system. Depending on the size of the system, this means considerable operating costs. Even in smaller systems, this may quickly add up to 12,000 $ to 25,000 $ per year. This is an amount which can be considerably reduced – even in case of well operated and maintained plants. This will also apply to your compressed air system without a doubt! Which are your actual costs per generated CF air? Which ener- gy is gained due to the waste heat recovery? What is the total performance balance of your plant? 42 www.cs-instruments.com/us

What is the differential pressure of individual filters? What is the humidity (pressure dew point)? How much compressed air is con- sumed? Although compressed air is one of the most expensive forms of energy, there are often enormous energy losses in factories, espe- cially in this area. They are mainly caused by the following fac- tors: • Disuse of the waste heat • Leakages of up to 50% • Missing compressor control system • Compressed air losses Lots of systems are not adapted to the actual demand or they are in need of repair. Leak curing programs could save about 1,7 million tons of carbon dioxide emissions per year. (Source: Fraunhofer Institut, Karl- sruhe, Germany). So there is a considerable amount of pos- sible energy savings slumbering in the compressed air lines of lots of enterprises. To tap into this, the heat generated during compressed air generation should be used to heat the space or to heat water. Furthermore, it is important to optimise the control of compressed air stations because this will lead to considerable energy savings in any case. Also the restoration of an ailing or no longer suitable compressed air supply will pay off after only a short period of time. Losses due to leakages within the pipe net- work incur high costs. This table shows the annual energy costs incurred by leaks: Chart recorder Energy loss at 87 psi (kWh) 0.3 3.1 8.3 33.0 12 bar (kWh) 1.0 12.7 33.7 132.0 Cost at 87 psi ($) 12 bar ($) 174 1.798 4.815 19.146 580 7.368 19.552 76.586 Hole diameter Inch 0.0016 0.0047 0.0079 0.0120 Air loss at 87 psi (1/s) 174 psi 1.2 11.1 30.9 123.8 (1/s) 1.8 20.8 58.5 235.2 In addition to the evaluation of standard sen- sors such as for example: • • • Flow meters, Pressure dew point, Pressure, • Differential pressure, • Absolute pressure, • Temperature sensors The connection of all kinds of third-party sensors such as: (Optik) • • • • • Pt 100 Pt 1000 0/4…20 mA 0-1/10 V pulse • RS 485 Modbus etc. is also possible. One of the main advan- tages of DS 500 mobile is the possibility to connect not only clamp-on ammeters but also external power meters, water meters or heat meters. As such, the current costs can be included very accurately in the analysis and typical figures of a compressed air plant can be determined. (Source: compressed air efficiency, kW x $0.06 x 8000 working hours per year) Energy resources like electricity, water and gas are usually monitored and therefore the costs are transparent. Water consumption, for example, is pre- cisely measured with consumption meters. Contrary to compressed air, a water leak is visible for all to see straight away and therefore fixed immediately. Leakages in the compressed air network „blow out“ unno- ticed, even on weekends and during pro- duction stops. The compressors continue to run during this time just to maintain a constant pressure in the network. For mature compressed air networks, the leak rate can be between 25 and 35 percent. They are the most indus- trious consumers working 365 days a year. Not considered in these considerations are the costs of “producing clean and dry” com- pressed air. Refrigeration and adsorption dryers dry the air with significant operating costs, which then “blows out” uselessly. With ever-increasing energy costs, these potential savings must be used more and more to stay competitive within the market. Savings potential can only be exploited if the consumption of individual machines or sys- tems is known and made transparent for all. When introducing an energy management system according to DIN EN 16001, all con- sumers have to recorded in the first step. This gives the user an overview of what is being consumed. This transparency makes it possible to deliberately intervene and save energy. In compressed air systems this means, in the first step, to detect and eliminate leaks. Especially for the complete monitoring and consumption analysis of compressor sta- tions and compressed air lines we devel- oped a portable measuring system, the DS 500 mobile. DS 500 mobile meets with all requirements for analyzing a compressed air system. www.cs-instruments.com/us 43

Chart recorder DS 500 mobile enables an intelligent energy analysis in a quick and easy way. The data will be indicated immediately in the display. The measured data can be retrieved all over the world via the webserver, GSM module. How is this done in practice? With the additional „real consumption mea- surement“ the leakages and therefore the cost share of the leakages in comparison to the total costs in $ can be determined. For this purpose just the costs in $ per kWh (please consider day and night tariff) have to be entered. By means of a mathematical function typi- cal calculations can be carried out like for example: • Costs in $ per generated CF of com- pressed air • Specific output in kWh/CF • Consumption of single compressed air lines including summation • Indication of Min-Max values, aver- age value If the minimum values rise continuously over the years this is a clear signal that the leak- age rate increases. This can easily be deter- mined by carrying out the measurements in regular intervals. Consumption analysis including statis- tics at the touch of a button Besides the compressed air also all other energy costs like current, water, vapor etc. can be recorded in this evaluation. This cre- ates transparency. So all energy and flow meters for com- pressed air, gas, water, vapor and so on can be recorded and evaluated. The customer gets the costs in $uro. On the big 7" colour display with touch panel, all information is visible at a glance. By means of the evaluation software CS Soft Basic all data can be evaluated online at the PC via a USB stick or Ethernet. Additionally to the consumption analysis as daily/weekly or monthly report an alarm can be sent by e-mail or SMS in case of thresh- old value exceedance. Step 1: Measurement 2.3) Leakage calculation The leakage calculation is carried out during production-free time (shutdown, weekend, holidays). The flow meter VA 500 measures the actual supplied quantity. The compres- sor delivers compressed air during this down time, in order to maintain a constant pressure. According to statistics, even if production is carried out day and night, there is at least one short period of time during which all load is switched off. By means of this data, the software defines a calculated leakage rate and calculates the incurred leakage costs in $. Step 3: Evaluation at the PC with graphics and statistics 3.1) Entry of necessary parameters Specific data have to be entered before the analysis is carried out: • Selection of compressor type (load/ idle resp. variable speed drive con- trolled) • As well as entry of the performance data according to data sheet • Period of measurement • Costs in $ for 1 kWh It is a special advantage that up to 12 com- pressors can be measured with one DS 500 mobile at the same time. Step 2: Analysis 2.1) Compressor analysis (current-/ power measurement) The energy consumption of every single compressor is measured by means of a clamp-on ammeter. The produced com- pressed air quantity is calculated by the software on a basis of the performance data of the compressor which have to be entered. • • • • • The following parameters are calcu- lated additionally: Energy consumption in (kWh), Load, Idle, Stop time, • Compressor load in %, • Number of load/unload cycles, spe- cific output in kWh/CF, • Costs in $/CF 2.2) System analysis (current measure- ment and real consumption measure- ment) The system analysis has the same function like the compressor analysis, however, it additionally offers the possibility to measure the actually produced resp. used quantity of compressed air by means of the flow sensor VA 500. 44 www.cs-instruments.com/us

Chart recorder 4) Measures Based on these analysis some measures should be carried out in order to optimize the compressed air system. These measures may differ from system to system, however, normally there are the following possibilities: • Please check whether there are leak- ages in the compressed air system and localize them. Usually they occur at weld seams and junctions. (50 holes with a diameter smaller than 0.039 inch may cause incur of $ 13,341per year). • By means of the load/idle analysis and the pressure profile the com- pressor regulation and adjustment should be optimized. Modern com- pressor operation systems help to minimize the idle times. (During idle times, the compressor takes up about 30 % of the full load energy, however, it does not release any air) • Reduce the input temperature (a temperature reduction by about 50 °F can save 3% of the energy). • Optimize the pipe system by avoid- ing unnecessary pressure drops. 3.2) Graphic evaluation with day view and week view Everything at a glance: The user gets a day and week view of all stored measured data with his company logo (can be easily integrated) at the touch of a button. By means of the zoom and the cross lines function peak values can be determined. 3.3) Compressed air costs in $ At the touch of a button the user gets all important data like e. g.: • Electricity costs • Compressed air costs • Leakage costs in $ • Compressor data with load / idle times • Specific output in kWh/CF • Costs per CF in $ www.cs-instruments.com/us 45

Dew point • Hygroscopic products (spices, sugar etc.) get stuck together during transport by the pneumatic conveyor system • Bubbles are formed during paint- ing and coating processes • Boreholes can clog up from dust being carried Tasks of dryers Different types of dryers are used in prac- tice in order to control the problems of moisture levels that are too high. In compressed air technology, the pres- sure dew point is the parameter for indi- cating the dryness of compressed air. The pressure dew point is the temperature at which the moisture which is contained in the compressed air condenses to form liquid water (also saturation, 100% relative humidity). The lower the pressure dew point tem- perature, the smaller the amount of water vapor contained in the compressed air. Usually, compressed air is generated from ambient air which must be aspirated, com- pressed by using pistons or screw com- pressors and which must then be dried more or less strongly. The aim is to produce dry and oil-free com- pressed air which is low in dust particles with the smallest possible effort. Residual oil and dust particles can be removed by means of complex filter systems. However, moisture must be reduced by means of dryers (refrigeration dryers, membrane dryers, adsorption dryers and so on) which ideally work in a controlled manner independent of any load. How does water get into compressed air? Air is able to bind more water vapor the higher the temperature and the larger the volume. Conversely, if the air is com- pressed, the capacity to bind water vapor is reduced. A compressor compresses atmospheric ambient air into a fraction of its original volume. At a certain point of the compres- sion process the water content of the air exceeds the decreasing ability of the air to bind water. The air is saturated and part of the water drops out as condensate. By means of an additional decrease of the temperature even more water will conden- sate. This means that the relative humidity on the output of a compressor will always be at 100 % and that there will be additional water drops in the outgoing air. The amount of liquid which drops out under pressure can be large. For exam- ple, a 30 kW compressor thus releases approximately 0.7 CF into the compressed air line at a humidity level of 60 % and an ambient temperature of 68 °F in eight hours. In case of big compressors this value will be much higher. Effects of the moisture content Depending on the application different demands are made on the compressed air. For each process the observance of a certain moisture content is the condition for a durably failure-free functioning of the whole system. Most of the compressed air lines are made from steel or non zinc-coated steel. Since the corrosion speed strongly increases from a relative humidity of 50 % this value should not be exceeded in any case. In the course of time, high moisture will lead to a corrosion in case of non zinc- coated lines. The rust gradually chips off and moves to the sampling points. This leads e. g. to blocked nozzles, defective control elements and production stops. Expensive repairs and short maintenance intervals are inevitable. In addition to prob- lems with corrosion and the described results the moisture content has direct influence on the quality of the final prod- ucts. Wich problems may arise in case of too high moisture? In the following please find some of the most occurring samples: www.cs-instruments.com/us 69 69

It is especially problematic (besides the already listed problems), if the condensate can concentrate in blind lines and does not drain off automatically. Condensate in blind lines can only be removed again by means of considerable efforts or dried and drained off by means of an extremely large amount of compressed air. This often leads to increased dew point values at very low consumption rates, without the refrigeration dryer showing any obvious problems. In this case, it is quite difficult for the person who is responsible for compressed air to find out the reason for the increased dew point values or in extreme cases for the condensate in the long-term. Adsorption dryers points -22…-40 Ftd. for typical dew The functioning of the adsorption dryer is based on the principle of the attraction between the two masses. Water vapor is bound (absorbed) at the surface of a des- iccant. Effective adsorption dryers are able to dry compressed air down to a pressure dew point of -40 °F and lower. Regenerative adsorption dryer exist of two tanks which are filled with desiccant. In dif- ferent procedures there is one tank regen- erated cold resp. warm while the other one dries the operation air. Depending on the procedure and the oper- ating conditions the desiccant has to be exchanged in cycles of three to five years. Certain operating conditions lead to a shortening of the life span of the des- iccant: • Overload on compressed air side due to excessive compressed air con- sumption • Poor pre-separation of condensate • Oily air • Regeneration times of the individual tanks too long New: DS 400 dew point measurement with alarm ensures process reliability Unique worldwide with 3.5" graphic display with touch screen and print function. An alarm delay can be set for each relay. This grants that only really long-term thresh- old value exceedances are indicated. Addi- tionally every alarm can be reset. Dew point Refrigeration dryer parameters around +35.6 Ftd. for dew point There are different types of compressed air dryers; refrigeration dryers or adsorp- tion dryers are the most commonly used ones. Refrigeration dryers cool down the com- pressed air to approx. 35.6 to 41 °F. In this case, the pressure dew point is also 35.6 to 41 °F. The excess water vapor con- denses and precipitates. After that the air is again heated up to room temperature. The refrigeration compressed air dryers are monitored in most cases only by a display of the cooling temperature. A sta- tionary humidity monitor is hitherto only installed in large systems or in particularly important applications. However, the display of the cooling tem- perature alone is not sufficient. Even if the cooling temperature seems to be OK, the following errors can cause an excessive pressure dew point: • Condensate in the refrigeration dryer is not drained off (conden- sate drain defective resp. soiled) • Compressed air bypass in the refrigeration dryer (close and cor- rode heat exchanger pipes and so on); compressed air bypass in bypass lines • A failure of the refrigeration dryer inevitably leads to considerable problems with condensate in the compressed air line 70 70 www.cs-instruments.com/us

For pressures of more than 232 psi, please use the high-pressure measuring chamber. The heart of the dew point sensor is the worldwide proven humidity sensor. In order to get quick and accurate measure- ments it is necessary that the humidity sensor is continuously flown by the gas (compressed air) to be measured. For this purpose a defined volume flow is blown out at a certain pressure via a capillary line. The measuring chamber can be con- nected to the sampling point without any large installation efforts by means of the standard plug nipple for compressed air lines. The big difference to customary paperless chart recorders is reflected in the simplic- ity of DS 400 on initiation and evaluation of the measured data. The intuitive operation with the 3.5" touch screen graphic display with zoom function and print key is the only one of its kind in the world in this price category. By means of the graphic display with zoom function the drying procedure resp. the dew point curve can be seen at a glance and stored in the data logger. So the user can take a look at the stored measuring curves also without any computer at any time on site. This grants a quick and easy analysis of the drying behavior. By means of the print key the actual screen can be stored as an image file to the internal SD card or to a USB stick and printed out at the computer without any additional software. Ideal for documentation of the measured values/measurement curves on site. www.cs-instruments.com/us 71 71

Flow [Thermal] Simple installation and removal under pressure 1) Even under pressure, the flow probe VA 500 is mounted by means of a standard 1/2" ball valve. During mounting and dismounting the safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure. For the mounting into different pipe diam- eters, VA 500 is available in the following probe lengths: 4.72, 6.30, 8.66, 11.81, 15.75 inches, (longer probes available on request). The flow probes are therefore suitable for being mounted into existing pipes with diameters of 1/2" to DN 300 upwards. The exact positioning of the sensor in the middle of the pipe is granted by means of the engraved depth scale. The maximum mounting depth corre- sponds to the respective probe length. (Probe length 8.66 inch = 220 mm maxi- mum mounting depth). 2) If there is no suitable measuring site with 1/2” ball valve, there are two easy ways to set up a measuring site: A Weld on a 1/2" screw neck and screw on a 1/2" ball valve BMount spot drilling collar incl. ball valve (see accessories). By means of the drilling jig, it is possible to drill under pressure through the 1/2" ball valve into the existing pipe. The drill- ing chips are collected in a filter. Then install the probe as described under 1). 3) Due to the large measuring range of the probe even extreme requirements to the consumption measurement (high volume flow in small pipe diameters) can be met. The measuring range is depending on the pipe diameter - see table on the right hand side. 1/2" mounting thread 1/2" - ball valve closed Installation depth = x + y dA = outer diameter x = dA 2 y x a d Engraved depth scale for precise installation 180 170 160 Safety ring A Screw neck B Spot drilling collars Drill under pressure with the CS drilling jig Flow measuring ranges VA 500 for compressed air (ISO 1217: 1000 mbar, 20 °C) Measuring ranges for other types of gas see pages 124 to 127 Inside diameter of pipe VA 500 Standard (304 ft/s) VA 500 Max.

Flow [Thermal] VA 521 - Compact inline flow sensor for compressed air and other types of gas No inlet section necessary – integrated flow straightener – sensor unit removable The newly developed VA 521 combines modern digital interfaces for connection to energy monitoring systems with a small, compact design. The VA 521 is always used when many machines (compressed air consumers) are to be integrated into an energy monitoring network. Readout values in the display can be rotated by 180°, e.g. for overhead installation Display shows 2 values at the same time: • Present flow in, CFM, l/min/m³/min • Total consumption (counter reading) in CF, l, kg • Temperature measurement Screw-in thread: Easy installation into the existing pipe due to integrated measuring section (suitable for 1/2", 3/4", 1", 1 1/4", 1 1/2" or 2" lines) Advantages at a glance: • Compact, small design - for use in ma- chines, behind maintenance unit on the end user • All interfaces are freely programmable via the display • Modbus-RTU output • 4...20 mA analog output for present flow • Pulse output total flow (counter reading), electrically isolated. Optional: M-Bus, Eth- ernet interface or PoE • NEW: Integrated pressure sensor (optional) Integrated flow straightener - no inlet section necessary With a key stroke: • Reset counter reading • Select units • Parameterise interfaces The sensor can be removed from the measuring section and cleaned.

VA 409 - Flow direction switch for compressed air systems Flow The thermal flow direction switch VA 409 with direction indication serves for determination of the flow direction of compressed air and gases especially in closed circular pipelines. By means of VA 409 with flow direction indication the flow direction of the compressed air can be determined quickly and safely. Compared with the former mechanical paddle flow switches VA 409 is able to detect even the smallest changes in the flow direction quickly and without any mechanical movement. The direction information in form of a potential-free contact (normally closed max. 60 VDC, 0.5 A) is transferred to the flow meters VA 5xx or to a separate building management system (BMS). Two LEDs show the flow direction. In connection with 2 flow sensors VA 5xx incoming and out flowing compressed air in closed circular pipelines can be measured precisely. Special features: • • • detects the smallest changes < 0.1 m/s relative to 20 °F and 1,000 mbar no mechanical wear parts easy installation under pressure TECHNICAL DATA VA 409 Response area detec- tion of direction: < 0.1 m/s relative to 68 °F and 1000 mbar Measuring principle: Calorimetric measurement Sensor: Pt 30/ Pt 700/ Pt 330 Measured medium: Air, gases Operating temperature: 32..122 °F sensor tube -4…158 °F housing Operating pressure: up to 232 psi Power supply: 24 VDC, 40 mA Current consumption: Max. 80 mA to 24 VDC Protection class: IP 54 EMC: Connection: 2 potential-free con- tacts: Housing: Sensor tube: Mounting thread: Housing diameter: in acc. with DIN EN 61326 2 x M12, 5-pin, plug A and plug B 2 x U max. 60 VDC, l max 0.5 A (normally closed); on request: Normally open Polycarbonate Stainless steel, 1.4301, length 629 inch, Ø 0.39, safety ring Ø 0.45 mm, lon- ger sensors on request G 1/2″ 2.5 inch Direction indication: 2 LEDs DESCRIPTION Direction switch VA 409 Mains unit in wall housing for maximum 2 sensors of the series VA/FA 5xx, 100-240 V, 23 VA, 50-60 Hz / 24 VDC, 0,35 A Connection cable for VA/FA series, 16 ft Connection cable for VA/FA sensors, 32.81 ft ORDER NO. 0695 0409 0554 0110 0553 0104 0553 0105 www.cs-instruments.com/us 121

If we talk about operating costs in com- pressed air systems, we are actually talking about the energy costs, Because the elec- tricity costs make up about 70-80% of the total cost of a compressed air system. Depending on the size of the system, this means considerable operating costs. Even in smaller systems, this may quickly add up to 2,000 $ to 25,000 $ per year. This is an amount which can be considerably reduced – even in case of well operated and maintained plants. In case of a three shift operation with 200 kW compressor performance a bad com- pressed air distribution can create redun- dant energy costs of more than 60,000 $ per year. This mainly relates to the detection of leaks and the correct design of the compressed air lines to minimize the pressure losses. Energy resources like electricity, water or gas are usually monitored and therefore the costs are transparent. Contrary to compressed air, a water leak is usually found quickly due to the visi- bility of the leak and therefore is fixed immedi- ately. Leakages in the compressed air net- work „blow out“ unnoticed, even on week- ends and during production stops. The compressors continue to run during this time just to maintain a constant pres- sure in the network. For mature com- pressed air networks, the leak rate can be between 25 and 35 percent. They are the most industrious consumers working 365 days a year. Not considered in these considerations are the costs of producing clean and dry com- pressed air. Refrigeration and adsorption dryers dry the air with significant operat- ing costs, which then „blow out“ useless through leaks. With constantly rising energy costs, these energy savings have to be implemented in order to stay competitive within the market. Potential savings can only be exploited if the consumption of individual machines or systems is known and made transparent for all. However, often there is no knowledge about the leak ratio. In the following we show you how leakage rate can be deter- mined easily in your company. Formerly the simple but inaccurate con- tainer method was applied very often. A simplified determination of the leakages is possible by means of the emptying of the tank. To carry out this measurement you just need a clock and a manometer. Furthermore you should know the storage volume of the tank as well as of the com- pressed air system. For measurement first the tank and the compressed air system are set to the upper cut-out pressure value. All compressed air consumers have to be switched off. Then the compressor is switched off and there will be no compressed air feeding into the system. Now the time T which elapses until there is a pressure drop of 1 to 2 bar due to the leakages is measured. The pressure drop between which the measurement is taking place can be selected freely. However, in practice the described method is very time-consuming, not adequate and inaccurate due to the following reasons: • • Storage volume, distribution pipelines cannot be determined exactly The accuracy of the differential pres- sure measurement and time mea- surement has to be observed • During the pressure drop, the com- pressed air volume cools down and therefore changes the volume flow reference value. An online measurement with con- sumption report is not possible. • This method belongs to the so-called indi- rect measurements, like also the method of the load and unload measurement during which the current intake is measured by means of clamp-on ammeters and cal- culated back to the volume flow over the technical data of the compressor. These indirect methods are antiquated and not suitable to detect leakages in the lower measuring range. Flow Determination of compressed air leak- ages with modern flow meters A modern compressed air consumption measurement resp. leakage measure- ment should be able to measure the real compressed air flow and also the smallest leakages quickly and reliably and record them. New: Flow measurement DS 400 for compressed air and gases Worldwide unique with 3.5 inch, graphic display with touch screen and print func- tion. With the new ”ready for plug-in” flow mea- surement DS 400 the current flow in CFM etc. as well as the consumption in CF or l can be measured. The new flow station works according to the approved calorimetric measuring prin- ciple. The heart is the flow sensor which has been proven and tested for years. It is characterized by a new thermally more efficient sensor structure which shown a higher chip temperature in case of same electrical connection values. Compared to other calorimetric measuring instruments the sensor has a considerably lower mass and therefore a faster response time. www.cs-instruments.com/us 133

Special features: • • 3.5" graphic display – easy to use with touchscreen Zoom function for accurate analy- sis of measured values • Consumption analysis with daily/ weekly/monthly reports • Colored measurement curves with names • Mathematical calculation function, e.g. addition of several consumers to a total consumption or energy costs per kWh/m³ • • • Print key: optional indications can be stored as image files directly on a USB stick and sent by e-mail with- out any software 2 alarm contacts for threshold value exceedance Freely adjustable alarm delay for both alarm contacts with reset function • Up to 4 sensor inputs for: addi- tional flow meters, dew point, pressure, temperature sensors, electrical effective power meters, optional third-party sensors can be connected: Pt 100/1000, 0/4…20 mA, 0-1/10 V, Modbus, pulse • Integrated data logger 8 GB • USB, Ethernet interface, RS 485 • Web server So the user can take a look at the stored measurement curves also without any computer at any time on site. This grants a quick and easy analysis of the compressed air or gas consumption. With the print key, the current screen can be saved as an image file on the internal SD card or on a USB stick and can be printed out without additional software on a PC. Ideal for documentation of the measured values/measurement curves on site. Col- ored measurement curves can be sent by e-mail as image files or integrated into a service report. The internal data logger enables the stor- age of the measured data for several years. The measured data can be evaluated via a USB stick of via Ethernet by means of the comfortable software CS Soft Basic. Particularly comfortable is the consump- tion analysis at the touch of a button. The CS Soft Basic automatically draws up daily, weekly and monthly reports. Flow An additional pressure and tempera- ture compensation is not necessary. The advantage is that the user can use the flow meters in different pressures and tempera- tures without any further compensation. In addition to compressed air, other gases such as • • nitrogen oxygen • CO2 • • • argon natural gas helium can also be measured. Threshold value exceedance can be reported optically and acoustically. 2 relays for pre- and main alarm are freely adjust- able. An alarm delay can be set for each relay. This grants that only really long-term threshold value exceedances are indi- cated. Additionally every alarm can be reset. The intuitive operation with the 3.5 inch touch screen graphic display with zoom function and print key is one of its kind in the world in this price class. The graphic display with zoom function shows the actual flow, the peak values and the leakage at a glance, the values are stored in the data logger. 134 www.cs-instruments.com/us

Installation VA 500 under pressure Flow VA 500 flow meter for compressed air and gases Even under pressure, the flow probe VA 500 is mounted by means of a standard 1/2" ball valve. During mounting and dismounting the safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure. For the mounting into different pipe diameters, VA 500 is available in the following probe lengths: 120, 160, 220, 300, 400 mm. The flow probes are thus suitable for being mounted into existing pipes with diameters of 1/2" to DN 1000 upwards. The exact positioning of the sensor in the middle of the pipe is granted by means of the engraved depth scale. The maximum mounting depth corresponds to the respective probe length. Inch 4.7 6.3 8.7 11.8 15.7 mm 120 160 220 300 400 Installation depth = x + y dA = outer diameter x = dA 2 Configuring the measuring site If there is no suitable measuring spot with 1/2" ball valve, there are two simple possibilities to set up a measuring location: Engraved depth scale for precise installation A B Weld on a 1/2" screw neck and screw on a 1/2" ball valve Mount spot drilling collar incl. ball valve (see accessories) 180 170 160 By means of the drilling jig, it is possible to drill under pressure through the 1/2" ball valve into the existing pipe. The drilling chips are collected in a filter. Then install the probe as described above. Due to the large measuring range of the probes, even extreme require- ments placed on the consumption measurement (high volume flow in small pipe diameters) can be met. (The measuring range depends on the pipe diameter). y x Safety ring www.cs-instruments.com/us 135

Compressed air quality Measure compressed air quality according to ISO 8573 Residual oil - particles - residual moisture Residual oil content measurement – OIL CHECK 500 For permanent and highly precise mea-sure- ment of the vaporous oil content from 0.001 mg/m³ to 5 mg/m³. Due to the low detection limit of 0.001 mg/m³, the compressed air quality class 1 (ISO 8573) can be monitored. Particle counter PC 400 The highly precise, optical particle counter PC 400 measures particles from a size of 0.1 µm and is therefore suitable for monito- ring the compressed air qual-ity class 1 (ISO 8573). Moisture – dew point sensor FA 510 FA 510 measures the pressure dew point down to -112 Ftd. Also in this case the conti- nuous measurement takes care that alert is triggered immediately if the compressed air dryer breaks down. DS 500 - the intelligent chart recorder of the next generation The centerpiece of compressed air quality measurement is the chart recorder DS 500. It measures and documents the measured data of the sensors for residual oil con- tent, particles and moisture. The measured values are indicated on a 7“ color screen. The curve progressions from the beginning of the measurement can be viewed by an easy slide of the finger. The integrated data logger stores the measured values safely and reliably. The threshold value can be freely entered for each measured parameter. 4 alarm relays are available for automatic alarm in case of threshold value exceedance. Optionally DS 500 can be upgraded with up to 12 sensor inputs. For connection to a PLC DS 500 has an Ethernet interface as well as a RS 485 interface. The communication is done via the Modbus protocol.

Leakage Leak detector LD 450 If pressurized gases escape through leaks in pipe systems (e.g. leaky screw con- nections, pipe corrosion etc.), noises are generated in the ultrasonic range. With the LD 450, even the smallest leakages, which cannot be heard by the human ear and which are not visible due to their size, can be detected even from distances of several meters. The LD 450 transforms the ultrasound, which is inaudible to humans, into audible frequencies. With the comfortable, sound-proof headset, these noises can be heard even in extremely noisy environments. The LD 450 leak detector is a further improve- ment on the proven predecessor models (LD 300 and LD 400) and impresses with its The LD 450 meets the requirements of class I instruments for the norm “Standard Test Method for Leaks Using Ultrasonic” (ASTM Int. – E1002-05) Acoustic trumpet significantly refined sensor technology and its improved support in the tracing of leaks. With the help of the integrated laser pointer, which serves for target heading, the leak can be localized more accurately.

This way you always have an overview of your consumption and costs and have them under control. You can choose between monthly, weekly or annual reports. The comparison function allows you to compare different time peri- ods so that you can recognise irregularities in your consumption, among other things. Graphic evaluation All measurement curves are indicated in colour. All necessary functions like free zoom, selection/dese- lection of single measurement curves, free selection of periods, scaling of the axes, selection of colours and so on are integrated: This view can be saved as a PDF file and sent as an e-mail. Different data can be combined in a shared file. Table view All measuring points are listed with exact time inter- val. The desired measuring channels with the name of the measuring place can be selected via the dia- gram explorer. Statistics All required statistic data are visible at a glance. So the user can see very quickly which minimal or max- imal measured values occurred when and for how long.
