With the Leakwise product line, GE Analytical Instruments has broadened its water quality measurement capability with break-through technology to monitor oil on water. As environmental concerns mount regarding our global water resources, Leakwise oil on water measurement systems provide state of the art solutions for the early detection and mitigation of water pollution events. Oil refineries, seaport authorities, water municipalities and power generation facilities represent a few of the industries benefiting from Leakwise technology.

The Leakwise oil detection sensors use high frequency electromagnetic energy absorption floating sensors, which enable reliable monitoring of hydrocarbon on water regardless of dirt or oil coating of the sensor or change in water level or water salinity.

The LEAKWISE ® ID-221 is installed in sumps and in groundwater monitoring wells to detect floating oil sheens resulting from leaking underground storage tanks and pipe-lines. It is also used to monitor hydrocarbons and other organic solvents during site assessment and remediation.

The LEAKWISE ® ID-223 can be installed in dry sumps to detect oil leakage or spillage from: above-ground oil storage tanks in tank farms, to detect oil leaks from transformers in sumps at power distribution substations, etc. It can also be used to monitor waste water discharge after treatment.
