Abstract
A flow rate meter is proposed, which serves to ascertain the quantity of a flowing medium, in particular the air quantity aspirated by an internal combustion engine via an air intake tube. The flow rate meter includes a measuring body (3) which is pivotable in a flow conduit (2) about a shaft (5) supported in the housing (1) counter to a restoring force in accordance with the quantity of medium flowing through the conduit. The lateral gap (15, 16) between the measuring body (3) and the lateral wall of the flow conduit (2) is narrower in the range of a slight deflection of the measuring body (3) than in the range of a greater deflection. As a result, air flowing via the lateral gap (15, 16) is prevented from impairing the measuring range of the flow rate meter, so that even very slight quantities of flowing air, such as those at low engine idling, can still be measured by this flow rate meter.
