This product uses NB-IoT low-power communication module with wide signal coverage and strong penetration capability, suitable for scenarios with weak signals such as underground pipelines and dense residential areas. It supports remote valve control function, allowing remote closing and opening of water supply valves for scenarios such as arrears shutdown and emergency water stop. It has a built-in water leakage detection function, automatically reporting an alarm when continuous micro flow exceeds 10 minutes, effectively reducing pipeline water leakage losses. The low-power design allows the 3.6V lithium battery to last up to 5 years. It has an IP68 waterproof rating suitable for underground pipeline installation, and supports remote firmware upgrade without on-site maintenance. It is compatible with smart water management platforms and can connect to existing water utility systems.
