Abstract

A volumetric-flow controller for adjusting a control flap is movably mounted within a flow channel. A measurement channel has a channel inlet and outlet for connection to the flow channel forming a separate bypass channel branched from the flow channel. A differential pressure sensor arranged in the measurement channel measures a differential pressure prevailing in the flow channel and outputs a corresponding electrical measurement signal. A control unit for electrically activating a flap drive in dependence on the electrical measurement signal outputted by the differential pressure sensor sets a desired volumetric flow rate in the flow channel. At least one air quality sensor arranged in the measurement channel measures an air quality prevailing in the flow channel and outputs a corresponding electrical measurement signal. The control unit electrically activates the flap drive in dependence on the electrical measurement signal outputted by the at least one air quality sensor.
