A flow rate meter having a temperature-dependent measuring element in which the device has a measuring conduit, which is equipped with a flow connection that extends from an inlet to an outlet, in order to cause some of the medium flowing in the measuring conduit, in the flow connection, to bypass the measuring element. The device is intended for measuring the mass of a flowing medium, in particular for measuring the aspirated air mass of internal combustion engines.
