Mass flow meter directly measuring flow according to constant temperature anemometer principle. The measured setpoint is compared with the nominal value. The valve will be readjusted accordingly.

Mechanical_Construction:
PVR31/32/34/36: mass flow meter and meter in the same housing
PVR 37: mass flow meter and meter together at the measuring bob
PVR38: mass flow meter and meter as single components are bolted together

Media: compressed air, air as well as virtually all gases and gas mixtures

Compensation: Neither temperature nor pressure have to be compensated. There are no moving parts within the flow meter, therefore it is virtually wear-free.

Pressure_drop: Low pressure drop because solely two stainless steel probes protrude inside the smooth, round measurement cell. The use of screw connections with a nominal size as big as possible is suggested.

Temperature_range: 0 °C to 50 °C / 32 °F to 122 °F
Operating_pressure: max. 10 bar
Differential_pressure: device dependent

Body: aluminium, optionally SST 316L
Elastomer: Viton®, optionally EPDM or Kalrez®
Sensor: stainless steel 316L
strainer: stainless steel
