I have a water meter (pictures below) i want to digitalize it. i want to create a board that read pulses and show the water flow on whatever app or integration i'll make
i just found about reed switches, and that could be possible to get pulses from the meter, but i don't know what to use and how to use the holes in the meter to accomplish that
ps: that is a gov meter so of course no datasheets or anyone to ask about the meter
Indeed, but even if the OP has got probes from the manufacturer in those threaded holes on the face, I would expect the meter reader to have a conniption whether they're legitimate or not. I like your idea of a secondary meter much better.
