The pulsed ultrasonic cross-correlation system is attractive for measuring the dynamic flow characteristics of two component liquid/gas mixtures because the sensors are invasive but do not extend into the pipe and, in contrast to previous continuous wave systems, have a uniform spatial sensitivity due to the absence of standing waves. The potential for measuring the flow characteristics in industrial processes including oil/gas risers is demonstrated by the measurement of the double peak cross-correlation function caused by the 'saddle' velocity distribution encountered in these risers. A theoretical model for the measurement of bubble velocity is developed and supported by experimental results.
