HFM500 thermal flow switch adopts the principle of thermal diffusion. The temperature difference between the two sensors can be used as the basis for measuring the flow rate. When the flow rate of the medium increases, the temperature difference decreases and vice versa. After processing, the temperature difference value is converted into standard electrical signal output and displayed.
