- FG-ODC is a digital sense cable for detection and location, along the entire length, of liquid hydrocarbons and liquid insoluble in water and their vapors.
It allows multiple leak detection and location thanks to independent digital addressing, enabled by an embedded microchip in each FG-ODC sense cable.
The sensor element is optimized for very fast response with light to middle distillates, and is sensitive to heavy oils such as conventional crude oils, dilbit / synbit, as well as to hy
FG-ODC
FEATURES
- Standard length (3 m, 7m and 12m) sensor sections or long line section allowing optimised system architecture.
- Microcontroller embedded in each FG-ODC sense cable allowing independent digital transmission to the alarm unit.
- Standard length sense cable provided with built-in plug-socket connector.
- Long line provided with built-in intermediate embedded connections (for each section), plus connector at extremities on demand.
- Structure of the sense cable comprising a silicon sensing wire, a continuity wire, a communication wire (proprietary bus) and the power supply wires. Protective external PE braid built on the cable.
- Intrinsically safe - can be used in classified areas: Ex ia IIB T4 Ga (IECEx “Zone 0”).
BENEFITS
- Reliable detection:
- Sensitive to heavy oils and vapors.
- Insensitive to water, inorganic pollutants and external loads (pressure).
- High sensitivity: examples of detection time: gasoline at 1-2 minutes (*), jet fuel at 4-10 minutes (*), diesel at 7-12 minutes (*), WTI: 20-35 minutes (*), Dilbit: 30 45 minutes (*).
- Detects and locates hydrocarbon leaks on the section length.
- Can be reused, allowing leak detection tests under real conditions.
- The same unit FG-NET can be connected to FG-ODC sense cables and mixed with water or acids / bases sense cables at the same time.
- Easy to install and remove: standard FG-ODC cables pre-connected with male / female connectors.
Note (*): depending on liquid composition and leak conditions
