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.
A measurement device for measuring an intake air mass along a flow direction (9) of an internal combustion engine, comprising a plate-shaped sensor element (2), which is inserted into a recess (17) of a sensor support (1) and has a membrane (4) that supports a measuring element (6), which membrane encloses a hollow space (5) embodied in the sensor element (2) on a side remote from the sensor support (1), wherein the sensor element (2) is secured in the recess (17) by a glue means provided between the sensor support (1) and a bottom face (29) of the sensor element (2) oriented toward the sensor support (1), the glue means having a glue seam (27;
