Abstract
For temperature compensation in a thermal mass flow meter with heated and unheated electric resistors which are interlocked to a bridge, a variable temperature-independent electric resistor is connected in parallel to the bridge. The sum of the current through the bridge and of the current through the resistor connected in parallel to the bridge functions as measuring signal.
