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.

 

Circular volume flow rate measuring unit for the measurement of volume flow rates in air conditioning systems, available in 7 nominal sizes.

For the manual volume flow rate measuring or for the permanent monitoring of the actual value signal.

Ready-to-commission unit which consists of the casing with an averaging differential pressure sensor.

Differential pressure sensor with 3 mm measuring holes, thus resistant to dust and pollution.

Both ends spigot with groove for lip seal, suitable for connecting ducts to EN 1506 or EN 13180.

Casing air leakage to EN 1751, class C.
