HW group WLD-ECHO

WLD-ECHO is a compact water leak detector supporting two external sensing cable zones. It detects even a few drops of conductive liquid any- where along the sensing cable (up to 185 m) and provides early warning via a built-in audible alarm and relay output.

Powered by either 2× AA batteries or an external power supply, WLD-ECHO offers flexible installation in data centers, server rooms, and other tech- nical facilities.

Fast detection requires no standing water level, ensuring reliable long- term monitoring. The device also signals sensing cable disconnection or damage. Zone 2 can be disabled when not in use.

With its dry-contact relay output, WLD-ECHO can be easily integrated into security or monitoring systems.

WLD liquid sensing (rope) cables provide continuous water leakage de- tection along their entire length. Water sensing cables cover larger areas and react much faster, even to just a few drops of water. However, water sensing cables require more careful installation.

Typical applications

• Liquid detection in buildings / technical sites
• Installation along walls and steps to protect rooms or entire floors
• Monitoring water leaks outside bathrooms in hotels
• Data centers - leak detection under raised floors and above suspended ceilings
• Server rooms / IT racks - early warning for leaks around cooling units and cable trays
• HVAC systems - monitoring leaks from A/C units, chillers, and condensation pipes
• Boiler rooms - detection of leaks from boilers, pumps, and valves
• Building basements - early detection of flooding or groundwater ingress
• Industrial facilities - monitoring around pipelines, tanks, and production lines
• Commercial buildings - installation along walls and floors to protect offices and common areas
• Hotels - monitoring bathrooms, corridors, and technical areas to prevent water damage
• Hospitals and labs - protection of sensitive areas with critical equipment
