Abstract
A method and apparatus for measuring the quantity of bubbles in a gas/liquid mixture. An ultrasonic wave is launched into the mixture and the magnitudes of two reflected waves are measured and compared. The logarithm of the magnitudes of the reflected waves is a measure of the quantity of gas content. The method and apparatus are suitable for measuring gas bubble content repetitively in a mixture turbulently flowing through a conduit.
