Volumetric flow controller VRAR Description A volumetric flow controller is used for pressure-independent volumetric flow regulation in ventilation and air-conditioning systems. It is used to keep the volumetric flow constant (CAV) within specified limits or to control it variably (VAV) as a function of a command variable, for example a room temperature controller, DDC or bus system. For constant volumetric flows, the operating stages CLOSED/Vmin/Vmid/Vmax/OPEN are available in stage operation, controlled via relays or switches. The housing, measuring sensor, control flap, PI controller...

Volumetric flow controller VRARTechnical data Volumetric flow range VRAR-A..., with electric controller NW (mm) VRAR-A..., with pneumatic controller Attention, the following specifications are important for the programming of the volumetric flow controllers: - this table merely specifies the complete measuring range of the controller (volumetric flow range) - If the customer absolutely wants a calibration curve different from 12 m/s, it must be specified! Once it is approved by the competent department, it can be adjusted correspondingly. - When the air volume drops below the Vmin shown in...
