Abstract
A two-phase fluid is rotated around a longitudinal axis so as to generate a coaxial flow having a tubular layer (15) formed by the gaseous phase surrounded by a tubular layer (16) formed by the liquid phase. The thicknesses of the tubular layers of the liquid phase and gaseous phase, and the flow velocity of at least the liquid phase (VL) is measured. The flow of each phase can then be determined from empirical data.
