GE-327 Thermal Flow Switch is based on two temperature sensors which are positioned within the fluid medium. The unheated sensor registers the liquid temperature. the other sensor is heated a few degrees above the medium, when the medium flows, the heat generated in the sensor is conducted away by the medium. The temperature of the sensor is measured and compared to the temperature of the medium. The state of flow can be derived by the temperature difference.Thermal Flow Controller Switches
