This series of smart remote transmission water meters developed based on NB-IoT communication technology. It features low power consumption, long-range communication, strong anti-interference capability, and stable data transmission.
Widely used in urban water supply, water resource management, agricultural irrigation, landscape management, industrial production, and industrial automatic control systems.
Residential
It adopts an ultra-low power pulse sampling method combined with a low-power NB-IoT transmission module. The external split design places the electronic unit in an independent fully sealed cavity with IP68 waterproof performance, while maintaining the structure and accuracy of traditional wet-type water meters.
