R160 Wet Type Valve Control Nb-Iot Residential Smart Water Meter 

1. The mechanical part of Residential Smart meter is multi jet wet type or dry type, with the high accuracy, low starting flow rate, easy reading, long lifetime, etc.
2. The Residential Smart water meter body can be brass/iron/plastic.
3. With valve control function.
4. Meeting EMC/ESD/EMI, the design requirements of electromagnetic compatibility for the electronic products, reaching the industrial leading level.
5. The wireless module is separated with the mechanical part, for easy maintainance.
6. The electronic parts are separately sealed, and the water proof grade can be IP 68.
7. Adopting the advanced technology of data coding and verification, with high communication reliability
8. Residential Smart  water meter is communicating directly with NB-IOT base station, without collector and concentrator as the reading system.
9. Combined by the host computer, building a remote reading management system, to ensure an automatic reading and monitoring.
10. Residential Smart Water meter data cycle reporting: it can be set up accordingly to report the data hourly, daily, monthly, including the accumulated water volume, battery capacity, meter status as well as the reporting period.
11. Convenient mechanical reading: the reading would not be affected after assembling the NB wireless module.
12. Stable signal: with the NB-IOT base station, NB Residential Smart water meter set up a network by the core network to make sure a stability of the signal.
13. Remote Valve Control: it can remote control the valve if arrears.
14. Shutting-off Valve when attacked: when the Residential Smart water meter is attacked by magnet or electricity, it will close the valve and alarm automatically.
15. Trigger/Button uploading: normally, the valve control Residential Smart water meter is in super low power consumption status. After triggered or pressed the button, the current data and working status could be uploaded by the module.
16. Shutting valve when of low battery: when the battery voltage is less than one certain number, the module can shut off the valve automatically, and upload the data.
17. Shutting valve when out of power: when the meter is out of power, the valve would be shut off and upload the data with the help of the Farad capacitor.
18. Detecting valve's breakdown: it will automatically judge whether the limit switch is working normally, and even if it is not working, the valve can shut on or off as normal. If the valve is wrong, the meter will alarm.
19. No wiring, and easy installation.

1. Low power consumption
2. Deep coverage of 20 dB and gain (more penetration of a wall than 2G).
3. Low cost, multilink (meter reports data directly to base station, without the help of the intermediate equipment.
4. Security (adopting cloud management platform to ensure the safety of the clients)
5. Reliability of internet (adopting the specific internet to ensure constant and stable operation.
6. Reusing the current cellular internet (fast and cheap).
7. Global standard cost and roaming.
