I can’t figure this out for myself. I had my Adeunis sensor connected to Sydney Water meter, Elster H400. All going good recording data. Then Sydney Water replaced the Elster meter with a different type, Arad Octave, which has an output module connected with 4-20 MA cable. The Arad manual refers to digital (pulse) output.
From reading Arad meter manual I am not 100% confident to confirm re-use of Adeunis sensor with Arad meter and correct wiring instructions for connection to Adeunis sensor in accordance with Adeunis manual.
I have attached manual for Adeunis sensor and Arad Octave meter.
