Product introduction
principle and characteristics. Based on the thermal principle, the sealed probe contains two resistors, one of which is not heated as the
detection resistor,and the other is not heated as the reference resistor. When the medium flows, the heat on the heating resistor is taken away, the resistance value is changed, and the difference between the two resistors is used as the basis to judge the flow rate. No moving parts, maintenance-free, easy installation, one model is suitable for a variety of pipe diameter requirements, switching continuously adjustable, extremely low pressure loss, compact structure, LED display flow trend, and switch status.
