ABSTRACT:
An apparatus and method for providing continuous phase proportion indications for a single component fluid having multiple coexisting phases. The apparatus assures homogeneity of the multiple phases by subjecting the fluid to an ultrasonic or sonic wave generator which uniformly disperses the phases among each other. The homogeneous phase mixture is exposed to a second sonic or ultrasonic wave generator with the speed of the wave originating therefrom being timed during its traversal across the mixture. Such timing enables determination of the acoustic velocity which, in addition to the wave's frequency and mixture's pressure, temperature and drop size can be correlated with the proportions of the phases in the mixture.
