LoRa wireless water meter adopts advanced wireless transmission technology, which transforms information from a conventional mechanical water meter into an electrical signal that is stored by the micro-electronics control circuit. It is able to automatically read the metering data via a wireless remote network and control the close and opening of the valve.
