Thermal dispersion flow switches measure the velocity of a liquid in a pipe or channel. The switch probe contains two basic components: a heating sensor and a temperature sensor. The heating sensor is positioned closest to the flowing liquid and provides consistent heat. The temperature sensor measures the temperature emitted from the heating sensor.
