Dragino SW3L-LB-020 is a battery-powered LoRaWAN® outdoor water flow sensor designed for remote water-consumption and flow monitoring in buildings, utilities, irrigation and IoT water-management applications. The 020 variant uses the DW-020 flow sensor with a G2" / DN50 connection, a working flow range of 10–300 L/min and a pulse constant of 12 pulses per litre. The SW3L-LB can upload accumulated water-flow volume and monitor continuous-flow conditions to help identify abnormal water usage or leakage. It supports LoRaWAN 1.0.3 Class A communication, Bluetooth 5.1 configuration, LoRaWAN remote configuration and wireless OTA firmware updates. Powered by an 8500mAh Li-SOCl2 battery and available with IN865 support, it is suitable for long-term indoor and outdoor water-flow monitoring deployments in India.
