LEAKWISE sensors use a patented, high-frequency Electromagnetic Absorption Technique to detect oil on water. Each floating sensor houses a high-frequency electromagnetic 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 LEAKWISE sensors not only enable reliable detection of hydrocarbons, but also provide valid indications of the thickness of the hydrocarbon layers and the percent of water in oily emulsions.
LEAKWISE sensors can also be used to detect the interface between any two immiscible liquids with different absorption rates. No other oil sheen monitoring system does this.
Principle of Operation
LEAKWISE is available in several application-specific models and configurations that have worked continuously for years in the following industries and applications:
