Volumetric flow controller VRAPPs

Domenii de utilizare:

For the control of variable and constant volumetric air flow in ventilation and air-conditioning installations with air loaded with aggressive media.

Funcţionare

The static volumetric flow controller regulates the air volume throughput either constantly or variably. Positive control to V_min, V_max or „CLOSED” is possible. 12 measuring points are  distributed on the measuring cross based on the median line method. In comparison with measuring rods having only four measuring points or measuring orifices, this gives optimum measurement results. The error of measurement is ± 5% of the rated volume.
