Overview

The NB-IoT Direct Reading Remote Water Meter is an advanced smart metering solution that integrates traditional mechanical water measurement with modern IoT communication technology. It is designed to simplify water utility management by enabling real-time remote monitoring, reducing manual meter reading, and improving operational efficiency.

Using NB-IoT cellular communication, the meter directly sends consumption data to a centralized system through telecom networks. This eliminates the need for local data concentrators, reducing installation complexity and maintenance costs. The device is built with low-power consumption architecture, ensuring long battery life of over 6 years under standard operating conditions.

It is widely used in smart city water systems, residential buildings, apartments, industrial facilities, and municipal water supply networks. The meter also supports prepaid management, alarm notifications, and remote configuration, making it a complete smart water management solution.
