HWg-WLD is a water leak detector connected to the Ethernet. The sensing cable detects as little as a few drops of a liquid, and can be also used to detect condensation. Whenever a liquid is detected, the device sends an e-mail or a SNMP Trap, or uses a central SMS gateway HWg-SMS-GW3 to send a text message.

By providing an early detection and warning, HWg-WLD can prevent damages and avoid the associated costs.

A built-in web server is used for configuring. The device can be monitored remotely over the internet.  It works with HWg-PDMS and HWg-Trigger.

  • 2 – 85 m (6.5 – 280 ft) long sensing cable can be extended using sensing as well as non sensing segments.
  • The sensing cable can be freely bent, twisted or even knotted, pressed or slightly pinched without raising a false alarm.
  • M2M communication protocols SNMP, XML and Box-2-Box allow integration into more complex monitoring systems.
  • Connected via LAN. Configuration via built-in web server.
  • The detection cable monitors even the smallest volumes of electrically conductive liquids. After being flooded with clean water it can be dried and reused.
  • Detected liquid leak as well as the sensing cable disconnecion sends an alert by e-mail, SMS, SNMP Trap, or activates a remote relay at a Poseidon2 of Damocles2 within the same LAN.
  • For Ring or SMS alarm use the HWg-Trigger software (external GSM modem required), or a HWg-SMS-GW3 gateway in the same LAN.
  • PoE (Power over Ethernet) version available.
  • With the HWg-PDMS software, logged data can be exported to MS Excel.
  • Compatible with a range of third party SW. Examples for programmers on using the product are available in the HWg-SDK (Borland C++, MS Visual, VB, C#, PHP, JAVA and more).
Applications and usage: 
  • Detection of water leaking from pipes (cable runs along the pipes)
  • Detection cable laid along the walls
  • Under raised floors
  • Above suspended ceilings
  • Detection of water leaks in drip trays
  • Detection of water leaks under A/C outlets

Water sensing cable

  •  The sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid anywhere on the total length of the cable.
  • The sensing cable is terminated with connectors.
  • The following can be combined:
    • Water sensing cable WLD - 2m
    • Water sensing cable WLD - 10m
    • Water sensing cable WLD - 50m
    • Prolong cable - 5m
  • The sensing part of the cable can be up to 85m (280ft) long.
  • The cable can be extended anywhere (even between sensing segments) with a 2-wire cable (max 100m – 330ft).
  • The WLD water detection cable is reusable (needs to be dried)

Box-2-Box mode

HWg-WLD can directly control relay outputs over the network. No additional software is necessary.

  • Supports any Poseidon or Damocles unit
  • State is transferred upon changes as well as periodically (default period is 30s). Uses XML over http.
  • The output must be in the "Manual" mode (no local condition for activating the output)
  • The user configures the remote device IP & port and the remote output ID (ID 151 = Output 1, 154 = Output 4)
  • If the relay is write-protected with a password, the user sets the password for controlling the relay
  • Output control can be tested with the TEST button
