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 meter) 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.
