Water Cut Meter - Density Compensation Module

Drexelbrook offers a Density Compensation Module (DCM) for its Universal IV™ & V In-Line Water Cut Monitors (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 & V CMs are designed for high-accuracy water in oil measurement. The DCM allows the Universal IV & V CMs 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 V utilizes 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 V CM features an in-line probe design that allows it to analyze 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 V CM also offers the industry’s highest pressure and temperature capabilities (1500 PSI and temperatures up to 450°F) 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. 32°F to 212°F at ambient pressure).

Applications for the Universal V 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.
