In this study, our purpose is to obtain instantaneous and mean velocity profiles in a Taylor-couette vortex flow(TVF) by using a UTDC device based on a ultrasonic generator. The experiment was carried out with a small aspect ratio where the Ekman boundary layer was not neglected. The device has a radial ratio of 0.375, aspect ratio of 3 and the gap length between the inner and outer cylinders of 25mm. As the result, the velocity profiles and their absolute values were in good agreement with those obtained by the Ultrasonic velocity profiler (UVP). This measurement system was applied to the solid-liquid phase flow experimentally, and well measured even in the opaque dilute solution.
