This water meter is primarily designed for use in environments without any IoT signal coverage.
It establishes its own wireless network, utilizing collectors and concentrators for wireless connection, then uploads data centrally via network mode.
Adopting LoRa communication technology, the water meter transmits key data such as flow rate, battery voltage, and signal strength to the meter reading system via a concentrator, enabling efficient data collection, remote control, and fault alarm functions. Its split structure features an independently sealed electronic unit, ensuring stable operation while maintaining the structure and measurement accuracy of traditional wet-type water meters.
