QVM62.1 Air velocity sensor is used to control the air velocity to a constant value, or to balance out pressure fluctuations (supply or extract air control), or to monitor the flow in air ducts. It primarily is used for modulating fan control in primary plants to set the basic volume flow. The QVM62.1 records the air velocity as a measured value and converts it to an active DC 0...10 V output signal.
