ABSTRACT:
An apparatus for measuring the mass of a flowing medium, in particular for measuring the aspirated air mass of an internal combustion engine. The apparatus has a hot wire disposed in the flow of the medium, the temperature of which is regulated in accordance with the mass of the medium; and its resistance is regulated by an adjustment variable which is a standard for the mass of the medium. The hot wire is guided on a sensor ring, which is of plastic, via support points. The support points are each fastened with a fastening section in a fastening slit of the sensor ring extending in the axial direction, and they each have a guide section protruding into the interior of the sensor ring through a radial slit. A guide wire extending in the flow direction is fastened to each guide section. The terminal support points in like manner, have attachment sections by way of which an electrical connection is made with the hot wire.
