Volumetric flow controller
Maintenance-free, mechanical volumetric flow controllers of the VRS series for keeping predefined volume flows constant in ventilation lines.
Working principle - Maintenance-free volume flow controllers for position-independent installation as mechanical controllers for constant volume flows.
Application - Constant control at variable pressures in the pressure range from 30 to 500 Pa.
Density class - Leakage air flow according to EN 1751, class C.
Temperature range - Temperature range from 10 to +50°C.
Control - Flow rate accuracy of the set flow rate: approx. ± 10%* of the nominal flow rate.
Largely trouble-free incoming flows are assumed.
*Larger deviations at low volume flows - especially for small sizes. |
