Leakwise ID-227 for Marine Applications

The Leakwise ID-227 Sensor for marine
applications can handle waves up to 2 m (6 ft).

The Leakwise ID-227 Oil Sheen Sensor is designed for installation at offshore oil tanker buoy terminals, jetties, and piers to detect floating oil sheens resulting from oil spills or leaks occurring during the loading and offloading process. Additional applications include detecting and monitoring floating hydrocarbons in lagoons, lakes, rivers, open channels, large retention ponds, and near offshore oil rigs

The ID-227 System consists of a:   

    • Sensor with a high frequency transmitter mounted on a wave rider float
    • Separate controller
    • Cable connecting the sensor and controller (wired model only)

    The wave rider float is designed to maintain the position of the detecting antenna at the liquid/air interface, despite fluctuations in the water level due to waves and tide. It has two field adjustable alarm points:


    • Low oil alarm — Detection of a predefined layer of hydrocarbons
    • High oil alarm — Detection of a hydrocarbon layer at a second predefined thickness

    Leakwise ID-227 Specifications


    The Leakwise ID-227 Oil-on-Water Monitoring System is a wired model for marine applications. The sensor is connected with a cable to the PS-220 Analog Controller. (For wireless operation, see the ID-227WL Specifications page.) Specifications include:

    The ID-227 detects from 0.3 to 20 mm of
    hydrocarbon on water or brine.
