I have two styles of Hall-effect sensors - paddle-wheel (GREDIA GR-S403) and GREDIA YF-B5 with circular flow rotor) but the flow/no-flow data is confusing and not helpful. A pressure sensor would not work either because our water pressure is not constant.

I just would like to know when water is flowing so that I can determine if a hose has broken (or a rodent has chewed through the hose). This will be used in my garden watering project. Perhaps no one makes such an ON/OFF water flow sensor?

Any suggestions would be greatly appreciated.

Thank you.

For the sake of clarity - I just want to know when water is flowing. I am not interested in volume.

Thanks.

Update! I have recoded my original water flow sensor code and now its output makes more sense. I now see flow rates of either '0' or a numerical value (float) greater than zero (0) which is what my original code failed to output. I failed to understand just how these water flow sensors needed to be coded.

Thanks!
