Volumetric flow controller VHPR

Fields of application

For the regulation of variable and constant volumetric flows in ventilation and air-conditioning systems.

Function

The volumetric flow controller controls the implemented flow rate either in a constant or in a variable way. A positive control to V_min, V_max or “Closed“ is possible. The flow-optimized measuring cross with its measuring points distributed in accordance with the median line method enables very accurate measurement of the implemented volumetric flow and can be used already from air speeds as low as 0.8 m/s. Straight flow sections after bends are not required. The error of measurement is ± 5% of the rated volume.
