Measurements of the Dielectric Constant and Density of Fluids under High Pressure

Abstract

Apparatuses and methods for measuring the dielectric constant ε_r and density ρ for liquids independently under high pressure are reviewed. Some experimental results and correlation equations for ε_r and ρ with pressure p are also given briefly. Furthermore an apparatus is described for simultaneous measurements of ε_r and ρ for fluids under high pressure.
