Functional principle

The function of immersion flow sensors is

based on the thermodynamic principle. The

sensor is heated up by a few degrees Celsius

compared to the flow medium. If the medium

flows past the sensor, the heat generated

in the sensor is dissipated. The resulting

temperature is measured and compared with

the temperature of the medium. The flow

condition of each medium can be derived from

the temperature difference obtained. Thus,
