This water meter is the "top-of-the-line technology" in the field of smart water meters for civilian use. It adopts the most advanced "ultrasonic metering technology" and "NB-IoT communication technology", and is a benchmark product for the construction of smart water management systems.

This is a "fully electronic" smart water meter, which:

1. Measures water volume without mechanical movement based on the ultrasonic principle.
2. Automatically and regularly transmits high-precision data to the cloud management platform via the NB-IoT cellular network.
3. Achieves full-process digitalization, automation, and intelligence from measurement, transmission to management.

Combining the dual advantages of ultrasonic and NB-IoT, this water meter offers:

• Extremely high metering performance: fully electronic, wear-free, wide range, high precision, and particularly excels in micro-flow measurement.
• Ultimate convenience in management: automatic timed reporting, mobile payment by users, remote valve opening and closing, parameter setting, and fault diagnosis.
• Strong data value: data available at minute level, through analyzing high-frequency water usage curves, it can achieve precise leakage warning (continuous small flow), vacant house monitoring, water usage habit analysis, etc., providing a data gold mine for water companies' refined management and energy conservation.
• Excellent deployment adaptability: NB-IoT network coverage is good, and the water meter can be installed anywhere with signal.

This high-end water meter is not suitable for all scenarios but is mainly targeted at value scenarios with special requirements:

• High-value users or key monitoring points: large industrial and commercial enterprises, schools, hospitals, etc., which require high-precision measurement and data analysis.
• Core nodes for district metering (DMA) and leakage control: with its extremely high micro-flow detection capability, it serves as a monitoring meter at the regional entrance or key nodes to accurately locate leaks.
• Upgrading choices for old pipe network renovation and water-saving city construction: as a demonstration project or key node upgrade option.
• Scenarios sensitive to metering disputes or with complex water usage patterns: its objective and precise all-electronic metering data has stronger credibility.

The ultrasonic NB-IoT remote transmission water meter is the culmination and high-end direction of the development of intelligent water meter technology. It is not merely an "automatic meter reading tool", but also a precise data sensor and intelligent execution terminal installed at the end of the water supply network.

It resolves the measurement bottleneck of traditional mechanical meters through "all-electronic metering" and addresses the issue of real-time data transmission and interaction via "cellular IoT communication". Although it is currently mainly applied in high-end and critical scenarios due to its relatively high cost, with technological advancements and the scale effect, its cost is expected to gradually decrease, making it an increasingly important "neural terminal" in the future smart city water supply network and providing irreplaceable core value for the efficient and scientific management of water resources.
