Suitable for flow ranges from 50 l/min up to 500 l/min

ProFlow flowmeters operate on the sliding vane principle. The meter consists of a specially shaped housing in which a rotor can rotate freely. Two pairs of vanes are placed into four slots in the rotor.

The high accuracy of the flowmeter (down to 0.2% and repeatability 0.05%) is not influenced by process pressure or temperature, mechanical pipe strain or liquid turbulence.

ProFlow flowmeters are available in connection sizes from 15 mm up to 50 mm representing maximum flow ranges from 50 l/min up to 500 l/min.
