I've been struggling since years with my gas meter (an Actaris G4 RF1), actually counting with a IR sensor was not the best option. Mostly when the temperature rise the resistor vary and lead to false pulses.
Since few days i use a sensitive hall sensor that detect the magnet and perfectly fit my need, the Allegro A3213EUA-T/A3214. I think it was nice sharing the info, i guess it also work with water meters
Here's my installation :
