Dear sir,
It will be available for next days if you want to contact me......
The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.
This type of sensor can be found on different diameters, water pressure (MPa) and flow rate (L/m) ranges. Make sure to select one that will cover your needs.
For example , you can choose water flow meter with 20mm diameter, <1.75Mpa water pressure and ~30 L/m flow rate range.
I'm looking forward to hearing from you soon.
Best regards.
Thank you.
