Abstract
There is provided a method of measuring the physical properties of a two-phase fluid using at least one piezoelectric oscillator immersed in the two-phase fluid, the two-phase fluid comprising a gas fraction and a liquid fraction, the method comprising: a) measuring the resonant frequency of the or each piezoelectric oscillator as a function of time; and b) determining, from the or each resonant frequency, at least one physical property of the two-phase fluid to characterize the two-phase fluid.
