NB smart water meter is a low-power wireless remote water meter that integrates narrowband IoT technology. It remotely reads water meter readings through wireless means without the need for manual intervention. Compared with traditional pulse water meters, the NB smart water meter adopts an innovative split design, placing the electronic unit in an independent and fully sealed chamber, making installation and maintenance easier. At the same time, its waterproof rating is as high as IP68, ensuring its excellent durability.

Without changing the original structure and measurement accuracy of the mechanical water meter, NB intelligent water meter effectively reduces reading errors and achieves zero error electronic remote transmission of electromechanical conversion. Its low-power design endows the water meter with high sensitivity, high-precision measurement, low initial flow rate, strong anti-interference ability, and remote meter reading function, with a longer transmission distance.

Users can set daily or monthly reporting cycles for NB water meters through the intelligent meter reading system according to their actual needs, including cumulative water consumption, battery capacity, meter status, and reporting cycles.

The characteristics of NB water meters include:

1. Convenient maintenance: The electromechanical synchronous sensor is installed separately from the base meter, with strong interchangeability, and the battery is independently packaged for easy replacement.
2. Intuitive mechanical reading: The water meter is equipped with independent function pointers, and the installation of sensors does not affect the mechanical reading.
3. Stable and reliable signal: Utilizing NB-IOT base station networking, a stable network is established through the core network and sensors to ensure worry free signal transmission.
4. Wide coverage: Within the same frequency band, the signal strength of NB IoT far exceeds that of existing networks, expanding the coverage range by a hundred times.
5. Real time monitoring: Supports timed meter reading and can remotely send instructions to the water meter for timely handling of abnormal situations.
6. Easy installation and wiring: No need for advance wiring planning, saving installation and maintenance costs.
7. Management cost reduction: Remote meter reading improves management level and effectively reduces management costs.
8. Accurate calculation of tiered water pricing: The tiered water pricing system calculates accurately, making it convenient for management departments to charge fees.
9. Remote valve control: realize prepaid or remote control, as well as remote supply function, for departmental management convenience.
10. Automatic system time synchronization: Ensure that the entire network clock is synchronized and data is not lost.
11. Parameter customization: supports adjusting setting parameters according to operating conditions to meet diverse needs.
