Microprocessor Based Analyzers

---

Engineers from Phase Dynamics worked closely with a major oil company to develop and patent the use of "oscillator load pull" for the 0-4% measurement of water in oil and the 0-100% measurement in either the "oil continuous" or "water continuous" phases.

Phase Dynamics now offers these measurement products in various materials and design configurations for ease of installation in a wide variety of oil and gas applications. Typical installations include well testing, well automation, two phase separators, net oil measurement, pipelines, finished product measurements, and custody transfer.

All functions of the analyzers are accessed through the front panel by four push button switches. The LCD display indicates the measurement value as well as temperature, net oil, net water, phase of the emulsion, and salinity (full range only). The analyzer electronics are housed in a Nema 4X dust proof and rain-tight enclosure as a standard feature. Explosion proof, Class 1, Division 1, Group C&D or 19" rack mount enclosures are available as options.

The 4-20mA current output indicates instantaneous water content and is updated every second. The units will accept either a current analog or pulsed flow meter input to perform net oil and water computations. Digital communications and instrument control are also standard features.

The Full Range Analyzer measures over the full range of 0-100% water in oil or oil in water, and will indicate whether the emulsion is either oil or water continuous. Fundamental calibrations in the oil and water continuous phases are performed at the factory. A field adjustment for actual water salinity (for the water continuous phase) is accomplished via a single point field calibration.

The Low Range Analyzer measures small amounts of water in oil. Long term stability, reliability and repeatability are obtained by temperature controlled oscillator electronics, compensation for fluid temperature, and the rugged measurement section. The low range analyzers measure water in oil over the 0-4%, 0-10% and 0-20% ranges in many different applications.
