  • MJ-75z is equivalent to a 3/4″ water meter + a AMR130 (Automatic Reading Device with RS485 communication). No NRV (Non-Return Valve) is required for remote reading. Horizontal Inline mount with dial facing upwards. For installing vertically, please refer to DAE U-75 which can be installed in any position, vertically, horizontally, water flowing downwards or upwards, dial facing upwards, downwards or side-way. Good for outdoor use, pit application. 
  • 1 DAE CC2030 KIT Gateway can read 1 to 20 DAE meters with RS485 communication (like MJ-75z) remotely with cell phone, PC and generate billing report (2nd picture). One CC2030 Gateway can also monitor 20 different meters (water, electricity, and gas) simultaneously. No IT guy is required. Just connect wires as per a simple picture (5th picture) & ready to go.
  • For existing building, hard to draw cable between  water meter and CC2030 (close to your router), please choose 1 CC2030 KIT + 2 WSC500A RF Converters to connect the meter and CC2030 wirelessly. (3rd picture)
