The NB IoT water meter adopts the world's most advanced narrowband cellular communication technology, which has advantages such as deep network coverage, wide connectivity, and low power consumption. The communication is stable, reliable, and secure.
1. Adopting industrial grade NB IoT modules, the mobile card adopts industrial grade M2M IoT network card.
2. The replaceable lithium battery power supply structure has a battery life of over 8 years, and data can be saved for 30 years in case of power failure.
3. Remote prepayment, tiered water pricing function, supporting 5 levels and 6 prices. The settlement mode can be configured as monthly settlement, quarterly settlement, or annual settlement.
4. Periodic reporting with configurable reporting intervals, including daily water usage, cumulative water usage, and remaining amount (water usage) for the previous and current months.
5. Two window opening periods can be configured, during which real-time meter reading can be performed.
6. Attack alarm, low battery alarm, insufficient balance alarm, valve malfunction alarm, overdue fee alarm.
7. LCD display, real-time display of water meter usage, signal strength, battery level, valve status and other data information.
8. Non contact buttons, long lifespan, anti attack.
key technology
1. NB IoT technology provides deep signal network coverage (underground meter wells, pipeline wells, etc. can all be used normally), ultra-low power consumption, and stable and reliable communication.
2. Multiple anti water theft design: The battery automatically alerts and closes the valve during battery replacement, effectively preventing water theft.
3. Fully sealed technology: All circuits are sealed with polyurethane, with no exposed electrodes, good sealing performance, and can work stably in water for a long time.
4. Data automatic error correction technology: multiple data backups, intelligent analysis and error correction to ensure accurate and error free data.
5. Variable index storage technology: When the number of times a memory is used exceeds a certain value, it is automatically stored in a new memory to improve data reliability.
6. Hysteresis sampling technique: Filter and judge the sampled signal to effectively prevent errors caused by pipe section shaking and water hammer pressure.
7. Timed cleaning and rust removal technology: timed valve action effectively utilizes the instantaneous impact force caused by pipeline pressure to achieve automatic discharge and rust removal.
8. The valve core and body of the electric ball valve adopt a suspended structure, which is anti lock and non scaling, improving valve reliability and service life, reducing energy consumption, and increasing battery life.
