Feature(may vary by option.)

●U-75 is equivalent to a 3/4" water meter + a AMR130(Reading Device with RS485 communication). For Cloud Metering with CC2030 + U-75, meter reading will always be same as reading of cell phone, PC. 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 U-75) remotely with cell phone, PC and generate billing reports. (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)
●Accuracy: +/-1.5% within normal flow rate range as per AWWA Standard. Conforms to AWWA C715, Safe Maximum Flow Rate: 20 GPM, Recommended Maximum Continuous Flow Rate: 10 GPM, Minimum Test Flow Rate: 0.25 GPM Normal Test Flow Limits: 1-20 GPM
●Factory Calibration Certificates available. DAE Controls LLC is a Minority Business. NMSDC Minority Supplier Certificate is available in DAE Controls Website.

NRV is not required

NRV (Non-Return Valve) is not required for DAE Cloud Metering with 1 CC2030 KIT + Encorded meters like MJ-75z, MJ-100z or Ultrasonic meters like U-75,U-100.

UL2464 Shielded Twisted Pair Cable with Drain Wire, 24 AWG

To securely transfer metering data for DAE Cloud Metering, please use UL2464 cable to extend connection (at least 2000 ft) between CC2030 and Encorded meters (like MJ-75z, MJ-100z) or Ultrasonic meters (like U-75,U-100).
