HFM510 digital display flow switch adopts the principle of thermal diffusion and is used in flow detection. The value of the regional temperature difference indicates the flow rate. Its working principle is to place a heating module and a temperature sensing module in a closed probe. The heat transfer temperature difference of the probe is closely related to the flow rate of the medium to be measured. When the medium in the pipe flows at a stable flow rate, the sensing module receives the sensing signal from the heating module is a fixed value. When the flow rate flowing through the probe changes, the thermal module will send out a temperature difference signal that changes accordingly, and the processor will output the result corresponding to the flow rate.
