LoRaWAN Non-Magnetic Coil Metering Module

The LoRaWAN Non-Magnetic Coil Metering Module is designed for smart meter manufacturers and retrofit projects that require accurate pulse detection and wireless data transmission in one compact PCBA. It combines non-magnetic coil metering with LoRaWAN communication, allowing compatible mechanical meters to detect pointer rotation and send metering data to an AMR / AMI platform.

The module is suitable for meters using a partially metallized disc pointer structure. With strong resistance to magnetic interference, low-power operation, and flexible mechanical-electronic separation, it can be used in smart water meters, gas meters, heat meters, and mechanical meter upgrade projects.
