Abstract
A flow rate meter for gaseous media has a pivotable member rotating about a shaft in a conduit carrying the medium. The force of the flowing medium pivots the member against a restoring force. The constriction of the stream generates a counter force which would make the displacement non-linear unless compensated. The compensation is provided by a vane which extends into a pocket of the conduit and defines two chambers which are connected to portions of the conduit upstream and downstream of the pivoting member, respectively. In a particular application, the flow rate meter is located in the induction tube of an internal combustion engine and is provided with fuel flow channels which meter out fuel in proportion to the pivotal displacement and deliver the fuel to the air stream through one or more nozzles.
