Leakwise
Oil-on-Water Detection and
Monitoring Systems

For the reliable detection, monitoring, measurement,
alerting, and control of hydrocarbons on water

Fact Sheet

What Leakwise Does for You

• Provides early warning by continuous, on-line detection of hydrocarbons
on water starting at 0.3 mm

• Monitors buildup of hydrocarbons on water

• Provides linear measurement of hydrocarbon layers in the range of
1–200 mm or greater

• Installs easily

• Operates virtually maintenance-free over extended periods of time

• Ensures reliable detection, regardless of:

- Coating of sensor with dirt or oil

- Changes in water salinity or temperature

- Variations in water table

• Conforms to EPA regulations

• Certified for operation in hazardous areas

• Specifications and performance tested and approved by the
German TÜV

• Offers convenient, user-adjustable set points of “Low Oil” and
“High Oil” for alarm and control

• Displays processor output with two relays and four indicator lights
(water/air/oil/ sensor disconnect); optional outputs include 4-20 mA,
RS-232/RS-422, a bar graph, and audio alarm

• Sends alarm and status messages via PTP radio or cellular communication
with optional wireless sensor

Leakwise is the most versatile and reliable sen­sor 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 con­sists of a wired or wire­less signal processor and
one or more sensors,
depending on your appli­cation 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, maintenance­free, without parts replacement.

World Class Technology

The Leakwise sensors use a patented, high­frequency 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 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.

The Leakwise sensors can be used to detect
the interface between any two immiscible liq­uids with different absorption rates. No other
oil sheen monitoring system does this.
