I. Introduction:

Water flow sensor consists of a plastic body, the flow of the rotor assembly and a Hall sensor.
It is installed in the water heater inlet end for detecting the flow of water when the water flow through the rotor assembly,
A magnetic rotor and the flow speed is adapted to change, the Hall sensor output corresponding pulse
Signal feedback to the controller, the controller is determined by the size of the water traffic regulation.
Caution:
Non-violent shocks and chemical erosion.
Prohibited throw or collision.
Vertical mounting inclination of not more than 5 degrees.
Medium temperature should not exceed 100 °.

Second, lead the way:

IN 1 red then positive
2 yellow OUT signal output line
3 black GND to negative

Third, the technical parameters
