Dragino SW3L-LB-010 – LoRaWAN Flow Sensor (G1” / DN25)

The Dragino SW3L is a rugged LoRaWAN water flow sensor designed to measure flow volume via pulse output and push the data to an IoT platform over a LoRaWAN network. It’s a practical fit for building water usage monitoring, remote sites, and any installation where you want reliable metering without running cables to a centralized controller.

Beyond reporting consumption, the SW3L can also monitor flow status and send alarm uplinks when it detects events that may indicate water waste—such as continuous flow that could point to a leak or a faulty toilet system. By default, it reports flow volume every 20 minutes, and key parameters can be adjusted depending on your network and monitoring needs.

For long-term deployments, the sensor uses an 8500 mAh Li-SOCl₂ industrial (non-rechargeable) battery, targeting multi-year operation (battery life depends on reporting interval and environment). The enclosure is weatherproof for indoor or outdoor use, and each unit ships with unique LoRaWAN keys preloaded—once those keys are registered on your LoRaWAN server, the device can join automatically after power-up.

Variant note: DW-010 flow sensor – connection G 1″ / DN25, 64 pulses = 1 liter.
