Abstract

A flow rate meter which serves to ascertain the mass of a flowing medium, in particular the flow rate of the air aspirated by an internal combustion engine via its air intake tube. The flow rate meter includes a measuring device that is pivotable about a bearing shaft in a flow conduit, in order to reduce the measurement error at maximum flow rate of the medium, a connecting conduit discharges downstream of the measuring device and its opening remote from the flow conduit leads into the damping chamber.
