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).
Here is a quick video tutorial of DPTV 2.
