Density Compensation Module Offered For Water Cut Monitor

AMETEK Drexelbrook (USA) now offers a Density Compensation Module (DCM) for its Universal IV In-Line Water Cut Monitor (CM). The module automatically compensates for density changes that may occur in the composition of products and reduces the calibration requirements due to those changes.

The Universal IV CM is designed for high-accuracy water in oil measurement. The DCM allows the Universal IV CM to maintain its stated accuracy with variations in density up to 10 API, ensuring measurement accuracy from load to load regardless of changes in product composition.

The Universal IV utilises an electrical measurement (capacitance) and correlates that to water cut (% of oil in water). Those measurements can be affected by changes in density. Density compensation is done to correct for changes in electrical properties that may impact output measurement and is particularly suitable for midstream refinery and oil pipeline operators.

Along with the optional Density Compensation Module, the Universal IV CM features an in-line probe design that allows it to analyse a large representative sample of flowing fluid in real time. Its sensing element extends into the main process line, taking an average of the capacitive property of the fluid over its entire length. That ensures a smoother and more accurate response, regardless of the mixture. The monitor’s onboard electronics then computes the relationship between capacitance change and water cut.

The Universal IV CM also offers the industry’s highest pressure and temperature capabilities (1500 PSI and temperatures up to 450oF) as well as field-proven Cote-Shield technology, which ignores coating buildup on the probe. In addition, a temperature-compensation (TC) version is available that measures product temperature internally and calculates a true water cut reading at any temperature as long as the water is in liquid state (eg. 32oF to 212oF at ambient pressure).

Applications for the Universal IV CM include automatic well testing (AWT), lease automatic custody transfer (LACT), basic sediment and water (BS&W), separation vessels, pipeline slug detection, truck unloading, pipe protection, dielectric analysis and machinery lube oil monitoring.
