Volumetric Flow Controller VARS

Domenii de utilizare:

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

Funcţionare

The VARS volumetric flow controller impresses with its simple design, high measuring precision and short length, meeting the majority of customary requirements of volumetric flow controllers. The volumetric flow controller allows the volume flow in ducts to be kept constant or to be regulated using positive control Vmin, Vmax or „OPEN” or „CLOSED”. It can also be used as a room or duct pressure controller.
In VAV systems the volume control damper can regulate variable volume flows between Vmin and Vmax depending on the supply air (room temperature controller). Volume flow set points Vmin and Vmax can also be altered at the controller at a later stage even after installation.
The measuring crosses each comprising 6 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.
