Phase Dynamics Water-Cut Analysers are precision real-time instruments developed specifically for use in the oil industry to measure the amount of water in oil pipelines. The Analyzers, also referred to as BS&W meters or basic sediment and water meters, are used in many applications including fiscal transfer, production monitoring, and well testing. The product line is based on the innovative sensing technology of oscillator load-pull. As the mixture of flowing liquids passes through the measurement section, the oscillator senses the entire cross-section of the material and instantaneously shifts in frequency as the material composition changes. This frequency shift is a direct measure of flowing material change within the measurement section. From a sensor technology perspective alone, Phase Dynamics sets the standard.
Phase Dynamics Water-Cut Analyzer
Phase Dynamics Water-Cut Analysers are precision real-time instruments developed specifically for use in the oil industry to measure the amount of water in oil pipelines.
Measuring RangeAnalyzers are available in six measurement range options to fit the application. For example, the Low Range Analyzer is typically used for custody transfer or pipeline applications whereas the Full Range is used for certain well testing and production applications where high water cut is present. The oscillators for each measurement range have been optimized to provide maximum load-pull to achieve best-in-class precision and repeatability. Measurement uncertainty is expressed as the 95% confidence interval or two standard deviations. Oø denotes oil phase, Wø denotes water phase. Inversion refers to the phase change from water-in-oil to oil-in-water. The Full and High Range Analyzers offer Heuristic Salinity© as a product option to maximize measurement performance in applications where salinity change is also a process variable.
