DIFFERENTIAL DIELECTRIC-TO-DENSITY MEASUREMENT FOR CRYOGENIC FLUIDS.

Author(s) : LIU F. F., CHOW S. W. H.

Type of article: Article

Summary

A HIGH-SPEED MICROPROCESSOR-BASED CRYOGENIC FLUID DENSITY INSTRUMENTATION IS DEVELOPED BASED ON THE RIGOROUS APPLICATION OF DIELECTRIC THEORY. THE OPERATING PRINCIPLE IS FORMULATED ON A NOVEL DIFFERENTIAL DIELECTRIC MEASUREMENT APPROACH WITH A NEW ALGORITHM WHICH PROVIDES FOR AUTOMATIC ADJUSTMENTS FOR POLARIZABILITY AND STRAY CAPACITANCE CHANGES. HIGH-PRECISION DIGITAL DENSITY MEASUREMENT IS ACHIEVED OVER A WIDE RANGE OF FLUID STATE RANGING FROM SUPERCRITICAL, THROUGH SUBCRITICAL TO SOLID FORMATION PHASES.
