Principle structure
Based on the thermal principle, a closed probe contains two resistors, 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 flow rate.
Characteristic
(1) Real-time monitoring of fluid condition in pipeline
(2) No moving parts, no maintenance and easy installation. One type is used for various pipe diameters.
(3) Provide switching output and display the fluid flow status in real time by 6 LEDs;
(4) The housing is a sturdy and well sealed aluminium alloy junction box.
(5) Low-power temperature sensor with high sensitivity and accuracy

Fit the flow switch so that the medium flows at the flow rate that needs to be monitored and adjust the potentiometer so that the first green LED just lights up.The switch then releases when the flow rate is below the current value.To make the switching point smaller than the current flow rate, adjust the potentiometer to make the green LED brighter.
