A study about size measurements of cavitation nuclei is performed, by comparing results from different techniques as Holography, Phases Doppler and Centerbody Venturi. These systems are installed in line. First, to calibrate the different systems, pressure distribution inside the Centerbody Venturi is determined, and response of the optical techniques is analyzed by injecting size calibrated latex particles. Then, the comparative measurements are performed for different hydrodynamic conditions and several cavitation nuclei contents.
