Calorimetric Flow Measurement

Calorimetric flow measurement is used to meaure the flow velocities of oily and aqueous media in closed piping systems. The respective sensors work in accordance with the calorimetric principle, which states that a flowing medium absorbs heat energy and carries it away. The sensor’s measuring probe is heated and the passing medium cools it back down again. The integrated temperature sensor detects the temperature of the measuring probe which is influenced by the flow rate of the medium. The medium’s flow rate is determined by comparing the actual temperature to the heating temperature.
