I’m also looking for a flow meter, but the only two-wire “pulse output water meter” I can find are on eBay and usually cost much more than AU$77. Most have a display, but I don’t need that – just digital output to my OSPI.
I came across much cheaper Hall Effect Flow Meters, but all of the 3/4″ ones are 3-wire. Would these work at all please?
This one appears to be a pulse output “turbine” with 3 wires.
Thank you in advance!
