Product Description
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.
- All-metal shell design, no moving parts, maintenance-free and easy to install.
- One model is suitable for various pipe diameter requirements. The switching value is continuously adjustable.
- Pressure loss low
- Compact structure. 6-LED displays flow trend and switching status.

How to adjust the flow ?
- Install the flow switch, remove the protection screw, make the medium flow at the flow rate that needs to be monitored.
- adjust the potentiometer and make the first green LED bright exactly.
To make the switch point smaller than the current flow rate, adjust the potentiometer to make more green LED brighter.
