The FG-NET digital unit is designed to be used for water leak detection, bases leak detection, acid leak detection and fuel leak detection. It is ideal for mission critical areas such as data centers, trading floors, semi-conductor plants. FG-NET unit can display a precise location (to the nearest metre) on a dynamic map. It detects simultaneous leaks hence avoid “a leak hide another” risk. Furthermore, the FG-NET digital unit can transmit the leak information to other LAN-connected equipments (such as BMS) via TCP/IP and JBUS/MODBUS communication protocols.


  • Precise location of a leak: to the nearest metre for water and acid leak detection and to the section for oil leak detection.
  • Each sense cable is addressable and can be assigned a specific name.
  • Multiple simultaneous leaks can be detected (120 cables = 120 alarms).
  • Different types of sense cables (for detecting conductive & non-conductive liquids) can be connected on the same panel for a truly bespoke system.
  • Cable break faults can be detected (to the nearest cable).
  • When a cable break occurs, the system maintains its integrity by continuing to monitor all preceding cables for faults.
  • Compatible with existing monitoring systems (Trend BMS etc.)
  • Extension and upgrade of the system is easy. No additional power source or zoning panels are required.
