If you explore this water flow sensor, you can find a magnetic core triggering action speed of switch as the rotating impeller rolls with the water flow. The flow rate change the speed. Its hall-effect sensor converts and allows the user to get the flow speed from pulse signal equivalent. You usually find this concept of detecting waterflow in dispensers and coffee machines.
Lots of water flow sensor are in the market with the size of your choice. Formulating the output of the water flow sensor: Water Flow = Pulse Frequency / 7.5. So, if you got 98 frequency reading, 98/7.5 = 13.1 (L/min).
