In this article, we review our experimental method for the viscosity measurement of supercritical fluid mixtures. We show some key points to consider in the construction of an oscillating disk viscometer. We discuss the role of density in the course of deriving the viscosity values from the Newell theory. Other important factors observed in the viscosity measurement for saturated liquid refrigerants near the critical point and aqueous solutions dissolving CO2 were also pointed out.
