Water flow sensor G1/4inch
Product information:
This water flow sensor consists of magnetic core, rotating impeller, external casing and sensor and a hall effect sensor. When water flows through the rotor, the rotor rolls, it activates the magnetic core to trigger the speed changes of the switch with different flow rate. The hall effect sensor outputs the corresponding pulse signals, users can get the flow rate by detecting the pulse. It is suitable for detecting flow in water dispenser or coffee machine.
There are also many other water flow sensors in other diameters for your choice.
The water flow sensor outputs a pulse proportional to the water flow with: Pulse frequency = Current * 98. That is, if the output frequency is 48, then the water flow is: 48/98 = 0.5 (l / min)
