The external diameter of thread the

connections use is 1.4mm.

Water Flow sensor

Water flow sensor consists of a

plastic valve body, a water rotor,

and a hall-effect sensor.

When water flows through the

rotor, rotor rolls. Its speed

changes with different rate of

flow. The hall-effect sensor

outputs the corresponding pulse

Signal.
