Volumetric flow controller VRAR

Fields of application

For controlling variable and constant air flow rates in ventilation and air-conditioning installations.

Function

The volumetric flow controller regulates the implemented flow rate either constantly or variably. Positive control to V_min, V_max or “Closed” is possible. The measuring crosses each comprising 12 measuring points, distributed in accordance with the median line method, enable a very accurate measurement of the air volume throughput. The error of measurement is ± 5% of the rated volume.
