Easy-to-use DPTV system for non-invasive measurements of water velocity in recti-linear flows (e.g Loligo mini swim tunnels), based on 2D video tracking of green laser illuminated flourescent sheres with neutral buyancy. The software will automatically calculate average flow velocity and direction within a user-defined area, e.g. swim tunnel working section.
Bright fluorescent green microspheres (dia. 212-250 µm) specifically designed with density 1.00 g/cc for suspension in fresh water, enabling flow visualization and analysis of fluid motion in flumes, flow tanks etc. The spheres exhibit a strong fluorescent response and are color stable in solution.
