ABSTRACT:
In order to determine the correct mass flow of a rapidly pulsating stream of fluid, in particular in the intake duct 10 of an internal combustion engine, a device for determining the mass flow and the direction of flow is proposed which has a temperature sensor 17, a thermoelectric mass-flow sensor 16 and two temperature-measuring elements 12, 14 arranged adjacent said mass flow sensor. One temperature-measuring element 12 or 14 is located in the feed stream and the other temperature-measuring element 14 or 12 in the discharge stream of the thermal mass-flow sensor 16, depending on the direction of flow.
