FG-ODC: High Sensitivity Addressable Oil Sense Cable

• FG-ODC is a digital sense cable for the detection and location of liquid hydrocarbons and liquid insoluble in water and their vapors, along the entire length.
• 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 a very fast response with light to middle distillates. It is sensitive to heavy oils such as conventional crude oils, dilbit/synbit, as well as to hydrocarbon vapors.
• Re-usable after leak detection.
• Can be installed in a humid environment, as it is insensitive to water and inorganic contamination.

FEATURES

• Standard length (3 m, 7m and 12m) sensor sections or long line sections allowing optimised system architecture.
• Microcontroller embedded in each FG-ODC sense cable allowing the independent digital transmission to the alarm unit.
• Standard length sense cable provided with the built-in plug-socket connector.
• Longline 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
