ABSTRACT:
A temperature-dependent measuring resistor layer is applied to a first carrier, the temperature and/or resistance of which layer is regulated in accordance with the mass of the medium. The first carrier is approximately rectangular and in particular is disposed parallel to the flow direction in a convergent section of the flow cross section. In a parallel section of the flow cross section, a second carrier having a compensating resistor is disposed, which likewise has a rectangular cross section and in particular extends parallel to the flow direction. An arrangement of this kind not only avoids deposits on the end face of the first carrier pointing into the flow but also prevents the result of measurement at the measuring resistor layer from being affected by the position of the second carrier in the flow cross section.
