The EASZ-1 oil/water monitor is a highly accurate online analyzer that is installed in a pipe and measures the amount of water in any oil or hydrocarbon under pressure. Water contamination in oil is often measured for various purposes to prevent loss of revenue, additive depletion, oil oxidation, corrosion, reduced lubricating film thickness, accelerated component wear rates, microbiological growth, increase/ reduction of dielectric constant and loss of power. Many of these problems can be averted in time by careful monitoring.

Determining the amount of water in oil in a pipe system can be a difficult task if it is not possible to know anything more than the water content at the time a spot sample was taken.

An electronic measurement is taken approximately every second by the EASZ-1, ensuring that more than enough data can be collected over a short or long time period. This enables users to monitor changes over time or an immediate event.

Continuous and accurate monitoring of water in oil contamination including lubrication oils, fuels and hydraulic oils, diesel and any oil based chemical. The EASZ-1 is a unique water in oil monitoring system which provides online water reporting for all types of Engine fuel or Lubrication, Pipelines, Turbines, Thrusters, Azipods, Gears, Separators, Vacuum Oil Dehydrators, Basket Type Oil Centrifuges, High Speed Purifiers and various Filtration Systems and Stabilizers with a means of continuous monitoring of the oil systems for possible water in oil contamination.

The EASZ-1 temperature compensated microprocessor based loop powered water in oil sensor enables fast and reliable drift free online detection and monitoring of moisture percentage or ppm water in oil.

The practice of measuring water

The industry standard practice has been to report water content as a percentage of the total volume or in parts per million (ppm) Since the EASZ-1 can directly measure the ppm or percentage water in oil in a process there are  enormous advantages for those wishing to correlate actual moisture readings with laboratory results.

The fact is, the EASZ-1 is more reliable than spot sampling or laboratory results, simply because it will be measuring the volume once a second, 24 hours a day!

The EASZ-1 can be calibrated to any type of oil and work reliably without the need for replacement due To element wear. The problem of drifting has been eliminated by the use of modern technology  digital circuits and years of successful research and development.

The practice of measuring water

The EASZ-1 is normally a quick ship item and can be retrofitted into existing oil systems either as a bypass instrument or in full bore inline versions.
