Abstract
A hot-film air-mass meter for measuring an air-mass flow which flows in the main direction of the flow, which can be used, in particular, in the intake tract of an internal combustion engine. The hot-film air-mass meter comprises a sensor chip having a measuring surface. The air-mass flow flows essentially parallel over one surface of the sensor chip. A flow separating element is mounted upstream from the measuring surface with respect to the main flow direction. The at least one flow separating element is designed in such a way that the air-mass flow is separated from the measuring surface of the sensor chip in at least one separation zone prior to reaching the measuring surface.
