The velocity vector of fluid is expressed with the function of the velocity components of three directions, and the function of time. Therefore, in order to understand the flow structure, it becomes very important to measure these components. We propose the new equipment that enables three-dimensional velocity vector measurement of the flow field of the name of Vector-UVP. It consists of a central emitter, symmetrically surrounded by three receivers. If the plane transducer is used for the emitter, the ultrasonic beam will spread in the practical range, consequently measurement volume will become too large. Thus, the characteristic of the ultrasonic beam from the emitter has great influence on the performance of Vector-UVP. For the solution of this problem, and in order to simplify our equipment, we use commercial focused transducer for the emitter. We developed 2D Vecotor-UVP system. And this system successfully applied to an actual flow field for two-dimensional velocity vector measurements.
