1 CC2030 KIT1 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 report. One CC2030 Gateway can also monitor 20 different meters (water, electricity, and gas) |
1 CC2030 KIT + 2 WSC500AFor 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. |
How to read the meter?Max. Reading: 9,999,999.9 gallons, Min. Reading: 0.1 gallons. The 1st digit from the right is in one tenth gallons. For example, if you see 0012345.6 on the screen, it is 12345.6 gallons. |

NRV is not requiredNRV (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 AWGTo 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). |
