FSM-15 Thermal Flow Switch adopts the principle of thermal diffusion. The temperature difference between the two sensors is 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. This product uses the all-metal shell design, 6 bit LED display and digital flow trend and switch state. The product potentiometer is simple to set up and easy to operate, without any internal moving parts, maintenance-free, can measure a variety of media.

The product is available in multiple configuration with Temperature and pressure integration.
