Dragino SW3L Outdoor Water Flow Sensor (LoRaWAN, NB-IoT & LTE-M)
The Dragino SW3L Outdoor Water Flow Sensor is designed for long-range, low-power monitoring of water flow and usage across LoRaWAN, NB-IoT and LTE-M networks. It is well suited to applications where visibility of water consumption, flow events, or abnormal usage patterns is required without relying on wired infrastructure.
Multi-Network Connectivity The SW3L platform is available in variants that support LoRaWAN, NB-IoT, and LTE-M, allowing you to select the most appropriate network based on coverage, installation environment, and operational requirements. This flexibility makes it suitable for private LoRaWAN deployments as well as carrier-operated cellular networks.
Designed for Outdoor and Remote Installations Built for outdoor use, the SW3L supports long-term deployment in exposed environments. It is commonly used for monitoring water flow in buildings, infrastructure, irrigation systems, and remote assets where regular manual readings are impractical.
Low Maintenance Operation Battery-powered and solar-powered variants are available, supporting extended operation with minimal maintenance. This makes the SW3L suitable for installations where access is limited or ongoing servicing costs need to be reduced.
Enhanced Monitoring with Telemetry2U While the SW3L can be connected to compatible third-party platforms, Telemetry2U is the recommended option for customers seeking a supported, end-to-end monitoring solution. When integrated with the Telemetry2U IoT platform, water flow data can be visualised on dashboards, logged historically, and used to trigger alerts for abnormal usage or flow events.

Combine Your Device with the Telemetry2U IoT Platform
Combine your Dragino SW3L device with the Telemetry2U IoT platform to bring water flow monitoring, alerts, and device management into one place. Telemetry2U helps you move from raw flow data to practical outcomes, with clear dashboards, configurable notifications, and tools that support day-to-day operations.
