Abstract

A device for measuring the mass of a flowing medium, with a temperature-dependent measurement element that substantially reduces measurement errors due to a pulsating flow that is characterized by means of flow fluctuations. The device has a measurement conduit which extends from an inlet to an outlet that is adjoined by a first section piece of a deflection conduit. The medium flows from the outlet to the first section piece and is deflected by an edge face into a second section piece of the deflection conduit. The edge face of the first section piece of the deflection conduit is embodied as inclined in relation to the flow direction in the measurement conduit. The invention is provided for measuring the mass of a flowing medium, for the intake air mass of internal combustion engines.
