The CMM 500 Compressor Master Meter is a new type of reference flow measuring device that has been specially developed for high-precision measuring of the capacity of compressors and for billing compressed air. The CMM 500 can be used both directly downstream of the compressor for measuring wet compressed air and as a compressed air meter for consumption measurement and billing of dry compressed air.

The large measuring span of 1:130 and an accuracy of <0.5 % of the measured value (0.2 Qmax to Qmax) are unique.

Service or maintenance can be carried out at any time via the mounting plate (zero point correction, condensate drain, sensor replacement for calibration), even during operation under pressure.

The portable flow meter PI 500 is an all-purpose hand-held measuring instrument for many compressed air and gas applications in industry like e.g.:

• Flow measurement
• Pressure-/ vacuum measurement
• Temperature measurement
• Moisture/ dew point measurement

The graphic indication of coloured measurement curves is inimitably. Up to 100 million measured values can be stored with date and name of measuring site. The measured values can be transferred to the computer by means of a USB stick. The data can be comfortably evaluated with the CS Soft Basic software. Measured data and service reports can be issued easily and quickly. The following sensors can be connected to the freely configurable sensor input of PI 500:

• Pressure sensors (high and low pressure)
• Flow sensors, VA 500 / VA 520
• Temperature sensors Pt 100, Pt 1000 / 4...20 mA
• Dew point sensors FA 510 / FA 515
• Effective power meters
• Opitonal third-party sensors with the following signals: 0...1/10 V, 0/4...20 mA, Pt 100, Pt 1000, pulse, Modbus

Each factory needs compressed air, however, often it is not realized that compressed air is one of the most expensive types of energy. Therefore, the intelligent use of flow measurement DS 400, holds an enormous potential for saving energy. In most cases the user mainly concentrates on the production, i. e. on the compressors. In order to save energy very often new compressors, control systems or heat recovery systems are installed.

The new 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 consumption sensors VA 500/ VA 520 or to a separate building management system (mbs). Two LEDs show the flow direction.

In connection with 2 consumption sensors VA 500/ VA 520 incoming and outflowing compressed air in closed circular pipelines can be measured precisely.

From recording of the measured data, indication on a big colour screen, alerting, storage up to remote read-out via webserver... this is all possible with DS 500. By means of the CS Soft Basic software alarms can be sent via SMS or e-mail. All measured values, measured curves and threshold exceedings are indicated. The curve progressions from the beginning of the measurement can be viewed by an easy slide of the finger. Daily/weekly/monthly reports with costs in € and counter reading in m³ for each consumption sensor are completing the sophisticated system concept. The big difference to odinary 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.

If we talk about operational costs of compressed air plants we are actually talking about the energy costs as they make up about 70 to 80 % of the total costs of a compressed air plant. Depending on the size of the plant this means considerable operating costs. Even in smaller plants this may quickly add up to 10 000 to 20 000 € per year. This is an amount which can be considerably reduced - even in case of well operated and maintained plants. For sure this also applies to your compressed air plant! Which actual costs per generated m³ air do you actually have? 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 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 at the PC.
