ID-221 Oil Sheen Sensor for wet sumps
The Leakwise sensors use a patented, high- frequency Electromagnetic Absorption technique. Each floating sensor houses a high-frequency electromagnetic energy transmitting and receiving antennas 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.
A Leakwise system consists of a controller and one or more sensors (also called detectors). The ID-221 sensor has a high frequency transmitter mounted on a float that maintains its position precisely at the liquid/air interface, despite fluctuations in the liquid level.
