1. Principle and structure:

Based on the thermal principle, two resistors are enclosed in the closed probe, one of which is 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 for judging the velocity.

2. Features:

(1) Conical probe design, can effectively prevent the winding material in the medium;
(2) Fully waterproof shell design, unique waterproof adjusting knob, no need to remove the sealing screw, can be adjusted arbitrarily, convenient and more reliable;
(3) Suitable for large diameter range of pipe, free to adjust the set point, optional anti-corrosion type, withstand voltage up to 100Bar, the indicator light directly shows the flow, optional relay;
(4) real-time monitoring of the liquid flow in the pipeline;
(5) No moving parts, maintenance-free, easy installation, one type is used for a variety of pipe diameter requirements;
(6) Continuous adjustable switching quantity, extremely low pressure loss, compact structure, simple appearance;
(7) two LED lamp beat conversion;
