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

  Powered by either 2 × AA batteries or an external 12 V DC supply, WLD-ECHO offers flexible installation in data centers, server rooms, and other technical 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.

  

  End user benefits

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

  Time does matter in context of water detection, WLD-ECHO should be connected to any long-term reliable alerting system.

  • Early warning – even the first drops of liquid are detected
  • No false alarms
  • Easy to install
  • Easy to connect with any dry contact based system (security panel)
