To show three dimensional flow structures is useful and effective when we treat with complicated flows such as bubble jets. A three-dimensional particle tracking velocimetry (3D PTV) is one solution, but has unknown factors. In the present study, we conduct the simultaneous measurements of 3D PTV with an ultrasonic velocity profiler (UVP) using the common tracer particles. The simultaneous measurements have other applicable possibilities, as well as accuracy check of 3D PTV. We tested four conditions I-IV of tracer particles. As a result, UVP is not applicable for small number of the tracer particles. On the other hand, 3D PTV is not applicable for large number of the tracer particles. We have found the optimum condition for both measurements, and confirm the accuracy of measurements.
