As I bought the sensors for Water and Gas, without checking if they could be used on my meters in Denmark, I now wonder if I can use the water sensor on the nummer 4 clam on the Flusometer, as a light sensor. My elektricity meter is a Kamstrup 382 DIN witch have a lightning pulse to show the consumption
in the future there will be a optical sensor ...
Port 4 is a generic pulse port with internal pull-up. You can indeed hook up an opto-sensor with open-collector output.
