The Dragino SW3L-NB is a NB-IoT Flow Sensor. It detects water flow volume and uplink to IoT server via NB-IoT network. User can use this to monitor the water usage for buildings.

The SW3L-NB will send water flow volume every 20 minutes. It can also detect the water flow status and send Alarm, to avoid the waste for water usage such as broken toilet case.

SW3L-NB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.

SW3L-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

SW3L-NB supports BLE configure and OTA update which make user easy to use.

SW3L-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

SW3L-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
