Water flow sensor consists of a plastic valve body, a water rotor, and a hall effect sensor – when water flows through, the internal rotator will change its speed with different rate of flow and hall effect sensor outputs the corresponding pulse signal. Use with laser cutters or CNC to measure if and how much water is flowing through laser tube or CNC spindle for cooling.
