Patent ID: 6945105

Claim:
Air mass flowmeter ( 10 ) for measuring an air mass taken in by the internal combustion engine, the flowmeter comprising: a sensor unit ( 24 , 26 ) that detects the mass of air passing by the sensor unit; a first and a second channel section ( 18 , 22 ) that direct an air flow from the first channel section ( 18 ) past the sensor unit ( 24 , 26 ); at least one turning area ( 20 ), having an inside and an outside with respect to a central point of a curve of the turning area, that connects the first and second channel sections ( 18 , 22 ) to each other; and at least one flow element ( 42 , 46 ) located at the inside of the turning area ( 20 ), and projecting into the turning area to separate the air flow from an inner wall of one of the channel sections upstream from the sensor unit.
