LFL10 Non‑Locating Leak Detection Controller is a cost‑effective and user‑friendly device for detecting liquid leaks. It features DIP switches on the front panel for flexible sensitivity adjustment, allowing it to adapt to diverse detection environments and standards. The device supports both relay contact and RS485 signal outputs, enabling integration with various monitoring systems for remote alarming and device control. Suitable for a wide range of applications—including IDC server rooms, data centers, smart buildings, libraries, museums, and warehouses—it provides real‑time monitoring and early warnings for potential leaks, effectively preventing property damage caused by water seepage.
RS485 communication for long‑distance, real‑time centralized data transmission
Adjustable sensitivity via DIP switches to suit various detection environments
Leakage triggers simultaneous local audible and visual (LED) alarms
Industrial‑grade components, easy DIN‑rail mounting; automatic fault reset
