GE Power & Water Water & Process Technologies Fact Sheet Leakwise TV* ID-227 Oil Sheen Monitoring System ^ ^1^^ for Marine Applications 4fr ^ ***** Wave Rider Float Sensor Applications The Leakwise* ID-227 Oil Sheen Monitoring System is a floating sensor capable of monitoring hydrocarbons or other organic solvents on water. The ID-227 is designed for installation at offshore oil tanker buoy terminals, jetties, and piers to detect floating oil sheens resulting from spills or leaks occurring during the loading/offloading process. Additional applications include detecting and monitoring floating hydrocarbons near offshore oil rigs, lagoons, lakes, rivers, open channels, and large retention ponds. Leakwise ID-227 System Description The ID-227 System consists of a: Sensor with a high frequency transmitter mounted on a wave rider float Օ Separate controller (see reverse for controller options) Cable for connecting the sensor and controller (wired model only) The wave rider float is designed to maintain the position of the sensor at the liquid/air interface, despite fluctuaխtions in the liquid level due to waves and tide. The standard PS-220 Analog Processor has two field adjustable alarm points for: ͕ Low oil alarm Detection of a predefined layer of hydrocarbons ו High oil alarm Detection of a hydrocarbon layer at a second predefined thickness The controller is a separate unit. See reverse for controller options and specifications. The Leakwise ID-227 can detect a minimum of 0.3 mm (0.01 in) layer of oil on water reliably, repeatedly, and without false alarms. It monitors on-line changes in oil layer thickness up to 20 mm (0.79 in). The signal processor relays can initiate both local and remote alarms, as well as control. Continuous built-in diagnostics monitor sensor operations. Principle of Operation The Leakwise ID-227 sensor uses a patented, high-frequency Electromagnetic Absorption Technique. The floating sensor houses a high-frequency electromag-netic energy transmitter and a receiving antenna which continuously monitor the liquid surface. Since water absorbs more electromagnetic energy than hydrocarbons, changes in the absorption rate of water indicate the presence or buildup of hydrocarbons. The ID-227 Leakwise sensor can be used to detect and mon-itor the buildup of free or emulsified non-soluble hydro-carbons on water and other aqueous solutions. No other oil sheen monitoring system does this. GEAnalytical Instruments, Inc.
