ABSTRACT:
An apparatus for measuring the mass of a flowing medium and a method for producing the apparatus are proposed in which a plate-like carrier on which at least one resistance coating is applied. Continuous fastening openings are provided in the carrier and the resistance coating such that they extend parallel to one another and at the same distance from one edge of the carrier. Rigid electrical connections are inserted through the fastening openings and are soldered provisionally with the resistance coating. A source of current is applied to each of the electrical connections for heating the connections to such an extent that the solder between the electrical connections and the resistance coating melts, causing the carrier located in a steady laminar flow to rotate into a streamlined position. The heating current is then interrupted, and the solder, as it sets, fixes the carrier in this streamlined position at the electrical connections.
