Calorimetric Flow Measurement

Calorimetric flow measurement serves to determine the flow velocities of oily and aqueous media in closed piping systems. The calorimetric principle is used for such calculations. It 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 velocity of the medium. The medium’s flow velocity is determined by comparing the actual temperature to the heated temperature.
