LoRa / NB-IoT Non-Magnetic Sensing Remote Water Meter

Non-magnetic sensing remote water meter designed for accurate and stable data collection in municipal and utility metering systems. Based on a rotor-type mechanical meter, it uses non-magnetic sensing technology to eliminate magnetic interference and ensure reliable measurement.

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

Designed for long-term operational stability, the solution enhances data reliability in environments where magnetic interference may affect traditional metering methods.

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