    摘要： A device is provided for determining a mass flow of a first gas flowing in a flowing channel of an internal combustion engine of a motor vehicle. The device includes: sound transducers arranged at respective ends of a measuring path for providing sound signals, a temperature sensor for determining a temperature of an overall mass flowing in the flow channel, and an evaluation unit arranged downstream of the sound transducers. The evaluation unit is capable of carrying out the following: determining a flow rate of the overall mass and a speed of sound based on delay times of the sound signals, determining an overall mass flow based on the flow rate, the temperature, and a pressure of the overall mass in the flowing channel, ascertaining a proportion of a second gas flowing in the flow channel at a temperature above 10° C. and based on the speed of sound and the temperature, and correcting the overall mass flow to obtain the mass flow of the first gas.

    摘要： An air mass sensor arrangement is disclosed. The air mass sensor arrangement includes a duct having a recess and an outer face; a sensor comprising a main body and a baseplate extending radially outward from the main body, the sensor being releasably attached to the duct by a screw connection so that the main body is partially inserted into the recess and the baseplate faces the outer face; and a sealing arrangement disposed around the recess for sealing between the duct and the sensor. The sealing arrangement includes a first web formed on one of the baseplate and the outer face and completely surrounding the recess.

    摘要： 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.
