Abstract
Mass-flow meter with temperature sensors, designed for measuring mass flow rates of liquids or gases, containing a heat conductive tube, through which the mass flow to be measured occurs and of which the beginning and the end are kept at the same temperature, as well as one or more means to raise the temperature in the tube and means to measure the temperature of the mass in the tube in different places. In or on the tube one or more facilities are applied with which the zero-offset of the means to measure the temperature can be eliminated in a physical instead of an electronic way.
