Hi @Dukereefnz, those look and sound like the correct type however they don't say Hall Effect so I'm not 100%, not really sure if there's different types. It talks about pulses per gallon, plus they mention it's just general purpose and show pic of connecting to a microcontroller so it should be ok.Hi Rob - looking at two of these.

is this correct?
these are 3/4inch.
thanks
This is the type I recommend, as you can see they are very similar to the H2Opro.
