4G Smart Water Flow Sensor – Long-Life, Remote Monitoring

This NB-IoT smart water flow sensor provides real-time water usage monitoring and waste detection, transmitting data directly to your IoT platform via secure MQTT, TCP, or UDP protocols. Designed for both indoor and outdoor environments, it operates reliably from -40°C to 85°C with a rugged, weatherproof enclosure.

Equipped with an ultra-low-power design and a high-capacity 8500mAh Li-SOCI₂ battery, it delivers multi-year, maintenance-free operation. The device can be configured wirelessly via Bluetooth v5.1 and supports OTA firmware updates for easy management. Data is sent at regular intervals, and alarms can be triggered for abnormal flow events such as leaks or faulty fixtures.

With multiple NB-IoT band support and optional integrated SIM card, this sensor offers plug-and-play deployment for a wide range of water monitoring applications — from residential and commercial water usage tracking to utility metering and wastewater management.
