GE Power & Water Water & Process Technologies Fact Sheet lwu r\vv iw ID-223 Oil Sheen Sensor Applications The Leakwise* ID-223 sensor detects the presence of and monitors the buildup of thin layers of hydrocarbons in wet and dry environments. Many petroleum and power companies have installed the ID-223 in wet or dry sumps for early detection, warning, and control of oil leaks and spills from:  Above-ground oil storage tanks Օ Transformer sumps in switchyards and remote power distribution substations  Oil/water separators Օ Cooling water systems and trenches  Storm water run-off Օ Wastewater sewer systems Other common applications include detecting and mon-itoring hydrocarbon leaks and spills in canals, retention ponds, and boiler condensate tanks. In addition, the ID-223 monitors wastewater treatment plant discharge to ensure regulatory compliance and can alert plant oper-ators of any upsets in the treatment process. | 'j I ID-223/500 The controller is a separate unit. See reverse for options and specifications. can also monitor on-line changes in oil layer thickness up to 25 mm (1.0 in). The signal processor relays are used for local and remote alarms, as well as control. A stilling well (available as an accessory option from GE) is recom-mended for ID-223 installations where lateral water velocity exceeds 30 cm/sec (11.8 in/sec). Continuous built-in diagnostics monitor sensor operations. The Leakwise ID-223 has three models: The ID-223/500 for water level fluctuations up to 500 mm (19.7 in), the ID-223/2000 for water level fluctuations up to 2,000 mm (6.6 ft), and the ID-223/2500 for water level fluctuations up to 2,500 mm (8.2 ft). Principle of Operation The Leakwise sensors use a patented, high-frequency Electromagnetic Absorption Technique. Each floating sensor houses a high-frequency electromagnetic enerͭgy transmitter and a receiving antenna which continu-ously 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 Leakwise sensors can be used to detect and monitor the buildup of free or emulsified non-soluble hydrocar-bons on water and other aqueous solutions. No other oil sheen monitoring system does this. A Leakwise system consists of a controller and one or more sensors (also called detectors). The ID-223 sensor has a high frequency transmitter antenna mounted on a float built in a guiding cage. The floating sensor main-tains its position precisely at the liquid/air interface, despite fluctuations in the liquid level. The ID-223 is controlled by the analog PS-220 Controller, which has two field adjustable alarm points for:  Low oil alarm ՗ Detection of a first predefined layer thickness of hydrocarbons  High oil alarm ՗ Detection of a hydrocarbon layer at a second predefined thickness, or detecting a dry sump situation in certain applications The ID-223 can detect as little as 0.3 mm (0.01 in) oil on water reliably, repeatedly, and without false alarms.
