    Picture of Flow Tracking System (DPTV)

    Flow Tracking System (DPTV)

    3,910.00 (EUR)

    Easy-to-use complete 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.

    Green laser pointer

    150.00 (EUR)

    Green 150 mW laser with SMA connector for connecting a fiber optic cable used in our DPTV (Digital Particle Tracking Velocimetry) system. The laser pointer comes with a rechargeable battery and charger. The laser is powerfull enough to light matches and is for professional use only. Leave it on for max 30 seconds at a time, and then allow min 30 seconds to cool down. Use protective glasses at all times. This is not a toy and it is MUCH more powerfull than a laser pointer used for presentations.

    Green fluorescent PE micro spheres

    175.00 (EUR)

    Bright fluorescent green microspheres (dia. 180-212 µm) specifically designed with density 1.00 g/cc for neutral buoyancy in freshwater, enabling flow visualization and analysis of fluid motion in swim tunnels, flumes, flow tanks etc. The spheres exhibit a strong fluorescent response and are color stable in solution.

    Fiber optic light guide

    220.00 (EUR)

    Fiber optic light guide  with steel housing and SMA connector for use with our DPTV (Digital Particle Tracking Velocimetry) system.

    Protection glasses

    40.00 (EUR)

    DPTV 2 loligo systems digital particle tracking velocimetry

    DPTV version 2 Digital particle tracking velocimetry software

    1,850.00 (EUR)

    DPTV 2 is fast and intuitive video tracking software for non-invasive measurements of water velocity in rectilinear flows. DPTV 2 is the ideal tool for water velocity calibrations in 170 mL and 1500 mL Loligo® swim tunnels and other Blazka-type swim tunnels with limited access or space for flow probes. The software is also part of our flow tracking system.

     

    The velocity measurements are based on 2D video tracking of green laser illuminated fluorescent spheres with neutral buoyancy. DPTV 2 will automatically calculate average flow velocities and direction from video images, and provide a calibration file that can be used directly in our different swim tunnel software. You can also perform a manual velocity calibration using recorded video files from your own camera or from a camera system from us.

     

    Please note that you will need a DAQ-BT device and one of our cameras to fully automate the calibration procedure in DPTV 2, and for real-time flow measurements.

     

    There is a free DPTV 2 demo available (see FILES/DOCUMENTS below).
