VA 520 - Mass Flow Meter for Compressed Air and Gas.

Our affordable mass flow meter for compressed air and gases works according to the approved calorimetric measuring principle. An additonal pressure and temperature compenstation is not necessary. Contrary to the previously used bridge circuit the newly developed evaluation electronics records all measured values digitally. This enables very precise and fast measurements.

Due to the new evaluation electronics, all VA 520 models have an integrated Modbus output as a standard. So all parameters can be easily transferred via Modbus. 

Due to its compact design it is possible to monitor all compressed air systems from the compressor to the smallest compressed air tool (1/4“ to 2 inch) with the new mass flow sensor VA 520. VA 500 flow sensors are available for larger pipe diameters from DN 50 to DN 300. Apart from compressed air also other gases like e.g. nitrogen, oxygen and CO2 can be measured.
