LoRa / NB-IoT Photoelectric Valve-Controlled Remote Water Meter

Photoelectric direct-reading remote water meter with integrated valve control, designed for accurate data collection and remote management in municipal and utility environments. Based on a stable rotary-wing mechanical meter, it uses non-intrusive photoelectric sensing to ensure reliable and precise consumption data acquisition.

Equipped with LoRa or NB-IoT communication, the meter enables wireless data transmission and supports integration with centralized systems and cloud platforms for automated remote meter reading and system-level monitoring.

The integrated ball valve allows remote control of water supply, supporting functions such as connection management and operational control within smart metering systems.

Designed for stable long-term operation, the solution supports scalable deployment across distributed infrastructure environments.

Compliant with GB/T 778.1–5-2018 and CJ/T 224-2012 standards, ensuring alignment with regulated water metering requirements.


Product Features

◎ It can periodically and actively report meter readings.

◎ It has remote valve closing and opening functions.

◎ This water meter supports prepaid and pre-purchased volume.

◎ It has a built-in early warning system. When there is low battery, abnormal metering, or when the pre-purchased volume and prepaid amount reach the threshold, it sends an alarm prompt. Different emergency water consumption can be set according to different users.

◎ It has a built-in memory with large-capacity storage function, which can store monthly frozen data for up to 24 months.
