Water Leak Sensor

The WLS-15-ULE is designed to detect water leaks and floods to prevent water damage. The WLS-15-ULE can be incorporated to detect water leaks around washing machines, water heaters, refrigerators, dishwashers, toilets, etc. to deliver early warnings. The WLS-15-ULE’s flexible deployment option allows for different situations and environments. The WLS-15-ULE can be mounted on the wall or deployed on the ground. Add-on optional extendable water probes or water sensing cables is for hard-to-reach areas and further increase detection area.

The WLS-15-ULE instantly sends an alarm signal when detecting the presence of water and generates a loud siren as well as flashes its red LED, providing effective audible and visual alerts to prompt a timely response. The reliable and robust protection the WLS-15-ULE radically reduces flood risks in any home and saves users the potentially exorbitant costs associated with water damage restoration.
