ABSTRACT:
A measuring device that is moved corresponding to the amount of medium flowing through a housing is provided for measuring the flow rate of a gaseous or liquid medium through the housing. The displacement of the measuring device represents a measurement of the amount of medium flowing through the housing and during the displacement of which, a movable part of a control valve is adjusted for metering a control medium volume that is proportional to the flow of medium in the housing. The measuring means is pivotably mounted at an upstream end to the housing and, at a downstream end, rests against the wall of the housing in its closed position. In order to provide an arrangement that is simple to manufacture and is not susceptible to momentary disturbances and which records the measured values exactly, the measuring means comprises a concavely shaped leaf spring which interacts with the flow of medium.
