Mass flow meter directly measuring flow according to constant temperature anemometer principle.
PVM 11 measures via a bypass, the other types measure the flow directly.

Features:
Low pressure drop and immunity against dirt and humidity. Measurement unaffected by pressure and
temperature changes. No moving parts, installation in virtually any position.

Principle:
Two stainless steel probes - a heater and temperature probe - protrude inside the bore. A constant
difference in temperature is created. The energy required is proportional to flow.

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

Applications:
Gas consumption metering, exhaust gas metering, semiconductor industry, analytical instruments,
N2/O2 generators, fuel cells, pharmaceutical, chemical, gas and food industries.

Conversion_factors:
The flow meter is normally calibrated on air. For other gases, a conversion factor must be applied.
The factor ist determined by applying a complex formula. The value is given below.

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

Body: aluminium, optionally SST 316L
Elastomer: FKM, optionally EPDM or Kalrez
Sensor: stainless steel 316L
Filter/strainer: stainless steel
