Title: Identification of fluids and an interface between fluids by measuring complex impedance

Patent ·
OSTI ID:7067430

Complex impedance measured over a predefined frequency range is used to determine the identity of different oils in a column. The location of an interface between the oils is determined from the percent frequency effects of the complex impedance measured across the interface. 5 figs.
