I have a (Schlumberger) RF1-G4 at home (Brussels) and I spent most of the week-end to try to get some pulse out of it with a reed sensor without any success at all...
Here is a picture of the meter: http://www.e-bulles.be/images/rf1-g4.jpg
(I used an Arduino board to detect the pulse)
So does anyone know exactly where the magnet is located? (which digit?)
(It says 1 pulse / 0,1m3, so it should be on the 2nd decimal...)
Maybe my reed switch is not sensible enough, I tried with what I had in my stock...
Other option would to test with hall sensor, just need to find a good one... (and Farnell is a pain for private users :( )
Any hint appreciated!
