Claim Text:
1. A method for determining the properties of a multiphase fluid comprising a liquid having at least one component and a gas, comprising: generating radial acoustic radiation forces in a first hollow piezoelectric cylinder having an axis, through which said multiphase fluid is caused to flow, such that said gas is directed away from the axis thereof and separated from said liquid; flowing said at least one component into a second hollow piezoelectric cylinder located coaxially with said first piezoelectric cylinder; generating acoustic standing waves in said at least one component; and measuring the frequencies and amplitudes of the acoustic standing waves from which the sound speed and sound attenuation of said at least one component from which said gas has been separated are determined; whereby the composition of said at least one component is determined.
