Microwave Methods for Cryogenic Liquid and Slush Instrumentation

Microwave instrumentation has been used to measure some of the properties of cryogenic fluids. The dielectric behavior exhibited by these fluids is the basis for using microwave systems to measure the densities and flow rates of nitrogen or hydrogen in either the single-phase liquid state or the two-phase slush state. These techniques are also applicable to measurements of the two-phase liquid-gas state, but were not investigated in this work.
