LoRa / NB-IoT Photoelectric Direct Reading Remote Water Meter

Photoelectric direct-reading remote water meter designed for accurate data collection and scalable deployment in municipal and utility metering systems. Based on a stable rotor-type mechanical meter, it uses non-intrusive photoelectric sensing to ensure reliable and precise consumption data acquisition.

Integrated with LoRa or NB-IoT communication, the meter enables wireless data transmission across distributed infrastructure environments. It supports connection to centralized systems and cloud platforms for automated remote meter reading and system-level monitoring.

Designed for long-term operational stability, the solution reduces reading errors associated with traditional pulse-based systems while supporting efficient large-scale deployment.

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