Water in lube oils can cause a lot
of problems. Even diesel engines (wet systems) cannot
have too much of it. Sometimes water can be added
to oil deliberately (such as cases involving theft
or negligence)
The presence of water can come from
a number of sources. These might include tank leakage,
tank condensation or deliberate causes.
Since profit margins can be severely
affected by water in oil, whether lubrication oils,
hydraulic oils, fuel oil, diesel , palm and vegetable
oil etc it is important to monitor the water content
either for auditing purposes or for the simple fact
that the water can affect the performance of the
machinery it is indirectly involved with.
Water in a lubrication system could
corrode metal surfaces and attack bearing substrates,
cause instability in the chemical additives of the
lubricants, form emulsions and encourage cavitation.
EESIFLO offers an affordable solution for online
monitoring of moisture or water content in oil.
The EASZ-1 can measure and report small amounts
of water by monitoring the changes in the dielectric
properties of the fluid passing through the instrument.
Thesensor works as a capacitance device where the
inner and outer tube sections form the two electrode
plates in a capacitor. The process fluids form the
dielectric.
The EASZ-1 measures the amount of energy that
can be stored in the process fluid currently within
the probe. The amount of energy that can be stored
is determined by the average dielectric constant
(DC) of whatever mixture currently within the probe.
Most Oils and Water have very different dielectric
properties-the typical value for oil is between
1.7 and 2.1. and water has a typical value of 80.
So, in other words, water is capable of storing
much more energy per volume unit than the average
oil.
The EASZ-1 is a simple to use instrument that
can be installed in no time and accurately reports
water content in a myriad of oil types. General
specifications are listed below but more information
can be obtained by contacting your local EESIFLO
