Flow sensors - Consumption measurement for various gases
The function of the flow sensor involves the calorimetric principle. The sensor is heated from the inside by a few degrees Celsius relative to the flowing medium into which it extends. When the medium flows, the heat generated in the sensor is dissipated through the medium. The temperature within the sensor is measured and compared with the medium temperature, which is also measured. The flow condition for each medium can be determined from the resulting temperature difference. The application of these sensors includes use as compressed air consumption meters.
