In this study, we aim to measure the concentration distribution of the dispersed emulsion in the vegetable oil. It uses the ultrasound flow velocity distribution measuring machine for the measurement. Ultrasound we be achieved speed in places where there is an emulsion because the reflection at the interface. Emulsion is not be measured speed in a place that does not exist. By utilizing this to verify whether possible to measure the concentration distribution of the emulsion. It uses a Taylor-Couette Vortex Flow(TVF) in stirring method in the experiment. First of all consider the method of dispersing uniformly water in the TVF. Next verify the optimal conditions in measuring the emulsion. This time it alters the 1,2,4,8 MHz the fundamental frequency of the ultrasound waves to be irradiated. The results of the experiment, and disturb the flow by the baffle is placed in the water after it has caused the TVF only oil water was found to be substantially uniformly dispersed in the oil. In addition, to measure the emulsion has been found that it is desirable to use ultrasound 4 MHz.
