HW group WLD: Water leak detector for a 2D area

• Water leak detection in an entire 2D area using several sensing cables
  
  
• WLD sensing cable can be easily extended and does not cause false alarms
  
  
• Detects even the smallest volumes of liquids, sensing cable can be dried and reused

• Alert the operator to the first few drops of water when a leak or flood occurs.
  Early warning in the first few minutes can dramatically reduce damages.
  
• The IP water detector is supplied with a 2m sensing cable that is easily installed at the place endangered by water.
• Whenever a flood is detected or the cable disconnected, you receive an e-mail or a text message (SMS).
• “WLD sensing cable A” is easy to mount, it can be freely bent and twisted. Even then, there will be no false alarms – common in other water leak detection systems.
• The water leak detection cable can be easily extended at multiple places using sensing segments or non-sensing extension segments.
• After flooding with clean water, the cable can be cleaned, dried and reused.
• The HWg-WLD water flood detector can be ordered as a PoE version and powered over the LAN cable.

Water flood detection in 1D or in 2D

• A spot detector (1D) is a simple and cheap solution.
• An area detector (2D) can alert the operator even to the first few drops of water.
• With an area detector, you can solve the source of the flood and avoid the consequences.

Examples of using the water flood detector

• Detection of water entering a server room
• Detection of a flood in a room in a 2D area (WLD sensing cable routed along the walls where water might enter)
• Detection of damaged pipes or valves and leaking water or coolant (water / ethylene glycol)
• Early warning by e-mail when a basement is flooded with water
• Pipeline leak detection and alarm (cable routed along the pipeline)
• SMS warning when a liquid is detected near rechargeable batteries
• Water detection in a 2D area under raised floors
• Detection of water leaks under air-conditioning outlets
• Detection of water flood in a freezing or cooling plant
• Detection of damaged heating pipes
• Environment monitoring in remote technology sites
• E-mail alarm when water is detected at the bottom of a shaft (pipeline leak detection)
• Water leak or flood detection anywhere in the building is signaled by an acoustic alarm at the guards' station or maintenance room

Water sensing cable for 2D detection

• "WLD sensing cable A" is available in several lengths (2 / 10 / 30 m) that can be connected as needed (max 85m).
• "WLD sensing cable A" can be extended with the WLD A prolong cable 5m (max 100m).
• "WLD sensing cable A" is a robust and resilient solution:
  • WLD sensing cable can be freely bent, there is no minimum radius to observe.
  • WLD sensing cable can be twisted or even knotted without giving false alarms.
  • WLD sensing cable is pressure-resistant, and even a slight pinch does not raise a false alarm.
• J-clips are included to mount the cable easily.
• Disconnection of the cable triggers an alarm similar to the flood alarm.
• After flooding with clean water, the cable can be cleaned, dried and reused.
• The non-sensing extension cable – “WLD A prolong cable 5m” – can be added.

Cable extension saves costs

• Flood detection must be placed near water sources: doors, windows, ascending pipes and branches.
• Non-sensing extension cable – WLD A prolong cable – can reduce the installation costs by 20–70% while maintaining the advantage of early warning to the first few drops of water.
• Three segments of the WLD sensing cable A are used: 2x 2m + 1x 10m.
• The entire cable in the picture forms one “zone” with three possible states – “OK”, “Flooded”, “Disconnected”.
• In a real installation, do not forget potential water sources “behind the wall”.
