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.
There is a free DPTV 2 demo available (see FILES/DOCUMENTS below).
Here is a quick video tutorial of DPTV 2.
Open flume tank system for force-swimming individuals or groups of zebrafish fry-juveniles (or similar) in a controlled recti-linear flow. Water velocity can be adjusted from 2-28 cm/s with a diaphragm valve or by changing the (included) pump flow rate. The exact flow is monitored in real-time with an inline paddlewheel (inductive) flow sensor and a transmitter with a digital display. Swimming animals can be filmed from left and right as well as from above and below. The open test section makes it easy to add or remove specimens. Typical applications include zebrafish phenotyping, swimming performance, exercise physiology, behavior etc. in freshwater or seawater species.
NOTE: The diaphragm valve and paddlewheel flow sensor is included. Mesh diameter size (in honeycomb and metal mesh) can be changed upon request. Contact us for more information.
