The WLD-ECHO is a compact water leak detector which can support two external sensing cable zones. WLD-ECHO can detect even a few drops of conductive liquid anywhere along the sensing cable, which can ran up to 185m in length. Water leakage alerts are provided via a built-in audible alarm and relay output. The WLD-ECHO is powered by either 2× AA batteries or an external power supply. WLD-ECHO 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 any monitoring, security or BMS system.
WLD ECHO Kits
The SET version includes the WLD ECHO, a 2+2m water leakage detection cable B, 2x AA batteries and a 12Vdc Wall plug adaptor. Additional or longer rope detectors, covers and tapes can also be purchased separately.

Tape and Cover Strips
The following tape and cover strips are available:
- WLD Poro Tape 5m white single-sided adhesive tape with holes, used to attach the WLD sensing cable to the floor or wall. The holes allow water to reach the sensing cable.
- WLD Cover Strip A-35 5m self-adhesive grey strip 35mm, for protection of the WLD sensing cable Type A on floors, stairs and similar surfaces.
- WLD Cover Strip B-30 5m self-adhesive grey strip 30mm, for protection of the WLD sensing cable Type B on floors, stairs and similar surfaces.
Operation Schematic
The sensing cable detects even the smallest volume of water, ethylene glycol and other conductive liquids anywhere on the total length of the cable. The cable is terminated with two connectors and can be combined with 2, 10 or 50m sensing cables.
