Product Description
Product Overview
LoRaWAN IoT water meter integrates mechanical base meter, electric ball valve, magnetoresistive sensor, MCU, wireless communication module, and control circuitry. Featuring mechanical-electrical separation design with high-capacity lithium battery pack for reliable power supply. Utilizes LoRaWAN wireless communication with spread spectrum technology for daily data transmission to gateway systems via LTE 4G or Ethernet networks. Dry structure design prevents fogging and condensation issues while maintaining measurement accuracy.
