摘要：A method and apparatus for measuring the quantity of bubbles in a gas/liquidmixture. An ultrasonic wave is launched into the mixture and the magnitudes of tworeflected waves are measured and compared. The logarithm of the magnitudes of thereflected waves is a measure of the quantity of gas content. The method and apparatusare suitable for measuring gas bubble content repetitively in a mixture turbulentlyflowing through a conduit.
