Abstract
An air mass flowmeter, suitable for connection to an air-intake manifold of an internal combustion engine, measures an air mass taken in by the engine. The flowmeter has an air passage consisting of a first channel and a second channel joined by a turning area. An air mass sensor is located in the second channel downstream of the turning area, on an inner wall of the second channel. A flow element is located in the turning area, projects from an inner wall of one of the channel sections towards a curved wall of the turning area to define a point of separation of a stream of air from an inner channel wall upstream of the air mass sensor.
