  • Oil Content Monitor Technology

    Fluorescence Technology

    Fluorescence is based on the principle that oil molecules absorb light energy at one specific wavelength and then emit energy at a longer wavelength. Fluorescence Detection Technology allows the monitor to discriminate between molecules of oil and particles of sediment, rust, etc, that plague the proper processing of an oily water separator.

  • Oil Content Monitor Certification

    Certification & Specifications

    The TD-107 Oil Content Monitor has been fully tested and certified by the USCG as a 5ppm or 15ppm bilge alarm for oily water separators under both IMO MECP 107(49) and IMO MEPC 60(33) resolutions. A universal power supply and configurable wiring allows it to be retrofit to any existing oily water separator.

    Shipboard Installation

    The TD-107 is installed with six mounting bolts and a simple ¼ inch sample line and atmospheric drain. Electrical connections are completed using two cables, a signal cable and a power connection to the universal power supply. NAG Marine will provide a drawing package and an engineer for complete installation if desired.

    Data Review Features

    The TD-107 features a USB data port for a simple download history of all ppm, alarm, and troubleshooting files. This data can be easily reviewed prior to any port state control inspections to verify corroboration with the ship's oil record book. NAG Marine can also provide a Client Login System to allow customers to store and download the data histories and certificates of their instruments.

Welcome to the internet home of the TD-107 Fluorescence Oil Content Monitor. Here you will find detailed information, videos, and photos about fluorescence oil detection technology, oil content monitor maintenance, oil content monitor calibration, and operation of the TD-107 OCM. Learn why Fluorescence Detection Technology is the only reliable way to determine oil content from a marine bilge oily water separator.

Unlike competing light scatter oil content monitors, the fluorescence detection technology of the TD-107 is resistants to false postives created by solids, rust, or other particles found in a typical ship's oily waste holding tank, bilge, or oily water separator. The TD-107 is tuned to ONLY detect the unique wavelength signature of fluorescing oil molecules, thereby allowing the efficent separation of bilge water through the ship's OWS.
