I have installed a fortrezz 3/4” flow meter before my house and irrigation water input. It uses a magnetic sensor with resolution of one pulse per 0.01 gallon, but instead of the usual two wire with bare ends, it has the magnetic reed sensor and a micro-usb plug (probably just hooked to the two data wires?) plugged into a z-wave powered wireless transmitter to send flow data to my home automation system.
although I can see irrigation water use in my home automation platform (SmartThings), I’d also like to see the flow data used for more accurate watering data/calculations.
I have limited experience with DIY electronics, so my apologies of this sounds dumb, but my thought was to install a second magnetic reed switch on the flow meter (close enough to get the signal but hopefully not affecting the original pulse reed switch cable) and run it back to my Rain Machine Pro 16. But then the sprinkler would also see/record regular home water usage as a leak.
I suppose I could try to figure out something with a transister/mosfet, to only allow flow pulses through when the mosfet is powered (perhaps using master control signal to provide the voltage necessary to activate, so that pulses only are received while on a watering program?). The easier thing would be if there was a setting to ignore non-active watering pulses on the RM, because even though I’ll know it’s not a leak, the type A need to have accurate data showing persists.
Has anyone else tried something like this, or have any recommendations?
