Principle of Operation
The Leakwise ID-223 Oil Sheen Monitoring System uses the industry leading technology of Electromagnetic Energy Absorption. The instrument consists of a very high frequency transmitter connected to a mismatched antenna. The antenna is immersed in the monitored fluids. The higher the energy absorption of the fluid, the more the loading on the antenna, and therefore, more energy which has to be supplied by the transmitter. Since water absorbs much more energy than do hydrocarbons and air, the loading in water is higher. If the antenna is surrounded by an oil layer or oil/water mixture, the loading is reduced in proportion to the reduction in water content. This unique, patented technique enables the detection of small layers of oil. It also enables continuous monitoring of oil layer buildup and the measurement of its thickness.
ID-223 Description
The high frequency transmitter antenna is mounted on a patented float built in a guiding cage. The floating detector maintains its position precisely at the liquid/air interface, despite fluctuations in the liquid level. It has two field adjustable alarm points for:
- Low oil alarm – upon detecting the presence of a first predefined layer of hydrocarbons
- High oil alarm – upon detecting when the hydrocarbon layer has continued to build up to a second predefined thickness
The ID-223 can detect as little as 0.3 mm layer of oil on water reliably, repeatedly and without false alarms. It can also monitor on-line changes in oil layer thickness up to 25 mm. The Signal Processor relays are used for local and remote alarm and control. Delay in the relays’ response time enables reliable detection regardless of occasional waves and/or turbulence. A stilling well can be used for extreme conditions. A built-in test feature is continuously monitoring failure free system operation.
Applications
To cover most applications the following ID-223 models are available: ID-223/500, ID-223/2000 and ID-223/2500. The ID-223 models can be installed in dry or wet sumps to detect oil leakage or spillage from:
- Above-ground oil storage
- Transformers in sumps at switchyards and remote power distribution substations
- It can also be used to monitor wastewater discharge after treatment.
Additional applications are available in detecting and monitoring floating hydrocarbons in: sewer systems, oil/water separators, cooling water trenches and canals, storm water run-offs, open channels, retention ponds, boiler condensate tanks and groundwater remediation system.
