    摘要: A measurement device for measuring the mass of a medium flowing along a flow direction, in particular the intake air mass of an internal combustion engine, has a plate-shaped sensor element, which is inserted into a recess of a sensor support. The sensor element includes a membrane that supports a measuring element, which membrane encloses a hollow space embodied in the sensor element on the side remote from the sensor support. The sensor element is secured in the recess by means of a glue between the sensor support and a bottom face of the sensor element oriented toward the sensor support. According to the invention, the glue constitutes a glue seam that extends around the hollow space of the sensor element between the sensor support and the bottom face of the sensor element and is only open on the side remote from the flow direction by means of at least one recess in order to ventilate the hollow space.

    摘要: In devices for measuring the mass of aspirated air of an internal combustion engine, for instance, via a line, it is already known to provide a tubular body inside this line and to provide a temperature-dependent measuring element inside the tubular body. In order that dirt particles and liquid droplets entrained by the aspirated air will be kept away from the measuring element, in accordance with the invention, a protective screen is disposed inside the tubular body, upstream of the measuring element; the screen extends in inclined fashion in the flow direction, and dirt particles and liquid droplets are deposited on it and carried to a downstream end of the protective screen, so that via an outflow opening they can reach the inner conduit wall of the tubular body and be made to bypass the measuring element.

    摘要: Devices for measuring the mass of a flowing medium using a temperature-sensitive measuring element have the disadvantage that considerable measuring errors may occur in the event of a pulsating flow characterized by flow fluctuations. In order to counteract these measuring errors, the device (1) possesses an axially extending measuring duct (33), in which a temperature-sensitive measuring element (20) is accommodated. The measuring duct (33) extends from the inlet mouth (36) to a deflecting duct (34), out of which the flowing medium flows out from an outlet orifice (46) without any axial distance from the inlet mouth (36) and radially underneath the latter. The invention is provided for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.
