Flow sensors - Consumption measurement for compressed air
The function of the flow sensor is based on the calorimetric principle. The sensor is heated by a few degrees Celsius from the inside relative to the flow medium into which it projects. If the medium flows, the heat generated in the sensor is dissipated by the medium. The temperature setting in the sensor is measured and compared with the medium temperature, which is also measured. From the temperature difference obtained, the flow condition can be derived for each medium. Applications for these sensors include measuring compressed air consumption.
