Method of, and apparatus for, measuring the physical properties of two-phase fluids |
摘要 |
<p>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 characterise the two-phase fluid.</p> |
