Electronic flow switch

Based on the thermal principle, in a closed probe contains two resistors, one of which is heated as the detection of resistance, and the other was not heated as the base resistance, when the medium flow, the heat resistance of the heat was taken away. Resistance value is changed . difference between the two resistors is used as the basis for judging the flow rate.
