GE P&W Leakwise Oil-on-Water Monitoring & Detection - Manual (Page 3)

Leakwise is the most versatile and reliable sen-
sor system available for oil-on-water detection
and monitoring. The Leakwise system can help
you avoid expensive downtime, regulatory fines,
and cleanup costs by:
• Detecting the presence of any type of
hydrocarbon on water immediately
• Monitoring the buildup of hydrocarbons
on water
• Measuring hydrocarbon layer thickness
with accuracy in the range of 1–200 mm
or greater
• Alerting facility operators of oil presence
or thickness with visual or audible alarms
and messages
• Controlling skimmers, discharge pumps,
and shutoff or diverter valves with a
remote or local relay contact
System Components
A Leakwise system con-
sists of a wired or wire-
less signal processor and
one or more sensors,
depending on your appli-
cation needs. The intrin-
sically safe sensors work in virtually any type
of water. They continue to work even when
coated with dirt or oil, thus eliminating false
alarms. In fact, Leakwise sensors are
designed to perform for years, maintenance-
free, without parts replacement.
World Class Technology
The Leakwise sensors use a patented, high-
frequency Electromagnetic Absorption
Technique. 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 pres-
ence or buildup of hydrocarbons.
The Leakwise sensors not only enable reliable
detection of hydrocarbons, but also provide
valid indications of the thickness of the hydro-
carbon layers and the percent of water in oily
emulsions.
The Leakwise sensors can be used to detect
the interface between any two immiscible liq-
uids with different absorption rates. No other
oil sheen monitoring system does this.
