• WIFI-LD (1)


Patented Leak Detection Delivered Via Wi-Fi

Whether you’re using a WiNG-MGR or a BMS system, the WIFI-LD allows you to leverage your existing Wi-Fi network to monitor for conductive fluid leaks in your facility.

The WIFI-LD continuously monitors your facility – it checks for leaks and ensures cable continuity once every minute and sends a packet immediately after detecting an alarm condition.

The WIFI-LD can be used in the following configurations:

  • With one SD-Z1 spot detector
  • With one SD-Z and up to 50 feet of leak detection sensing cable
  • With up to 100 feet of leak detection sensing cable

Integrates With Your Monitoring Systems

  • The WIFI-LD populates seamlessly into the WiNG-MGR’s user interface.
  • If you’re using a BMS, the WIFI-LD transmits leak status information via a UDP packet to your BMS.

Wireless and Battery Powered

RLE’s Wi-Fi sensors are compact and unobtrusive, yet provide an industry leading battery life – WIFI-LD sensor batteries will last up to FIVE with transmission every five minutes. No wires are required for power; no wires are required for transmission.

Designed With Security in Mind

  • Only allows one-way communications.
  • Supports WPA/WPA2‑PSK encryption.
  • Encrypted data storage for network and configuration information.
