This NB-IoT multi-jet water meter features an electromechanical separation structure, offering low start flow, IP68 full-sealed protection, and over 9-year battery life. It enables massive connections and remote meter reading without concentrators, providing a stable and reliable solution for smart water management.
1. A multi-jet rotor-type metering structure provides accurate metering, low starting flow, wide measuring range, low pressure drop, and high precision.
2. A separate electromechanical structure allows for flexible and convenient maintenance, simple meter replacement, and simple and convenient remote transmission. No complex wiring or installation is required, resulting in minimal engineering effort and low installation costs.
3. Based on NB-IoT communication technology and carrier network communication, it eliminates the need for a base station concentrator, simplifying initial commissioning and ongoing maintenance. It also offers long and reliable transmission distances.
① Massive connections: 50-100 times more connections than existing wireless technologies using the same base station.
② Ultra-low power consumption: Long battery life.
③ Deep coverage: A medium- and long-range communication technology, it offers longer transmission distances than GSM.
④ Security: Inherits 4G network security capabilities, supports two-way authentication and strict air interface encryption to ensure user data security.
⑤ Stable and Reliable: Provides carrier-grade reliable access, effectively supporting IoT applications and smart city solutions.
4. Data storage, capable of storing 24 months of historical data.
5. Power-off memory function, automatically resuming metering upon power restoration.
6. Completely sealed and waterproof, achieving water and electricity isolation with no exposed electrodes, IP68 protection rating.
7. Utilizes a low-power NB-IoT data transmission module, utilizing hibernation technology to achieve low power consumption.
8. Ultra-long-life battery pack: standard ER26500 battery + HPC1520 battery capacitor combination, with a battery life of over 9 years. Moisture-resistant and anti-static, effectively ensuring the lifespan of the water meter.
