    • Devices for determining at least one parameter of a medium flowing in a conduit, in particular for determining the air-mass flow in the intake tract of an internal combustion engine, including a conduit member and sensor device having a bypass section are already known. To prevent flow detachment at the side walls of the bypass section, it is proposed that a flow guide wall running substantially parallel to the side wall provided with the separation opening of the bypass section be arranged in the conduit member behind the separation opening, as viewed in the main flow direction; the length dimension b of the flow guide wall, as viewed in the main flow direction, being equal to or greater than the distance a of the separation opening from the rear wall; and the distance c of the flow guide wall from the center axis of the conduit member being greater than or equal to the distance d of the side wall provided with the separation opening of the bypass section from the center axis.

    • Known sensor supports have a recess in which a sensor element is glued by means of an adhesive. The device according to the invention has a plate-shaped sensor element that is accommodated in a recess of a sensor support. A sensor region (3) has at least one measurement resistor, which region is exposed to the flowing medium wherein a gap remains between the sensor element and the recess. To protect an evaluation circuit connected to the sensor element against moisture, the provision is made, according to the invention, that at least partial regions of the evaluation circuit and partial regions of the sensor element are covered by a protective coating, wherein the gap has at least one enlargement by means of which the flow of the protective coating can be influenced. The device according to the invention is used for measuring the mass of a flowing medium in the intake air mass of internal combustion engines.
