WL03A-LB/LS
LoRaWAN None-Position Rope Type Water Leak Controller
The Dragino WL03A-LB/LS is a LoRaWAN None-Position Rope Type Water Leak Controller. User can lay the WL03A-LB/LS + Water Leak Cable on the ground to detect water leakage. The water leak cable is sensitivity, when there is water over the leak cable. WL03A-LB/LS will indicates a water leak event and uplink to IoT server via LoRaWAN network. The WL03A-LB/LS will send periodically data every 2 hours as well as for each water leak event. It also counts the water leak times and calculate last water leak duration. WL03A-LB/LS supports BLE configure and wireless OTA update which make user easy to use.

Application guide
Choose the airflow range by deployment scenario

Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.

Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
