Functional description

The measuring unit is fitted with an effective pressure sensor for measuring the volume flow rate.

The effective pressure is either measured and evaluated manually, or transformed into an electric signal by a pressure transducer.

Volume flow rate range45 – 10100 l/s or 162 – 36360 m³/h
Measurement accuracy± 5 % of the measured value
Effective pressure rangeApprox. 8 – 200 Pa
Measuring unit differential pressure (pressure loss)17 – 32 % of the measured effective pressure
Operating temperature10 – 50 °C


Rectangular volume flow rate measuring unit for the measurement of volume flow rates in air conditioning systems, available in 39 nominal sizes.
