Description
Simple design to mount an inductive proximity sensor on your Elster V200 Watermeter. The sensor used is a “M12 DC 5V NPN NO LJ12A3-4-Z/BX-5V 300mA” sensor working on 5 volt. It triggers on the little red wheel in your watermeter and will generate one pulse for every liter used. You will also need a 10k pullup resistor as the sensor will pull the output low when proximity is detected).
