| Decription |
Volume flow controllers are mechanical system-powered controllers and were developed for the control of flow rates in constant volume systems. The controllers are suited for both supply air and extract air.
Each controller is set up to a reference flow rate and has been subjected to an aerodynamic function test. The required flow rate can be easily set without tools using an external scale. To simplify installation, the controllers can be ordered and fitted by nominal size. The required flow rate can then be easily and accurately set during commissioning.
The controller operates without an external power supply. A control damper blade, shaft mounted supported on bearings, is adjusted by the aerodynamic forces such that the preset flow rate is held constant over the entire differential pressure range.
Aerodynamic forces from air flow create a closing force on the damper blade. A self inflating bellows amplifies this force, acting simultaneously as an oscillation damper. This closing force is counteracted by a leaf spring that unrolls over a cam plate. The cam plate is designed such that as the pressure differential changes, the damper blade adjusts to keep a constant flow rate within close tolerances.
