CMM 500 – High-precision measurement of the compressor’s delivery capacity

The CMM 500 Compressor Master Meter is an innovative reference flow meter that has been specially developed for the high-precision measurement of free air delivery from compressors and for the billing of compressed air. The CMM 500 can be used both directly downstream of the compressor for measurement of wet compressed air, and as a compressed air meter for consumption measurement and billing for dry compressed air.

Its wide measuring span of 1:130 and a measurement accuracy of <0.5 per cent of the measured value (0.2 Qmax to Qmax) are unique.

Service and maintenance can be carried out at any time via the mounting plate (zero point correction, condensate drainage, sensor replacement for calibration), even whilst the system is in operation under pressure.
