Liquid flows found in environment related fields are often of complex nature, being multidimensional, transporting solid particles and gas bubbles, influenced by various external parameters.
Thanks to its versatility and capability to measure non intrusively particles-loaded and opaque liquids, UVP instrument is an alternative of choice to classical speed measuring devices (Pitot tube, current-meter) or optical instruments (LDA, PIV). It is indeed widely used in related research units, for instance related to hydraulics and earth science.
