The ability to obtain detailed velocity measurements and associated flow properties enables designers to enhance the aerodynamics of bodies and vehicles, from airplanes, ships and automobiles to micro-size devices.

Thermal anemometers provide accurate velocity measurements including velocity spectrum and higher order statistics in clean gas and liquid flows. LDV systems use laser beams to get accurate velocity measurements in gas and liquid flows, even in hostile environments. They also make non-invasive measurements in rotating machinery, especially, in the interblade region in compressors, turbines and fans.

PIV systems use a laser sheet to measure the instantaneous flow field in a desired region. Measurements provide vorticity, spatial velocity gradients and other variations. Repeated PIV measurements provide time-averaged statistics. Time-resolved measurements capture the temporal variation of the velocity field. PIV/PLIF systems add scalar properties (pressure, temperature, etc.).

TSI CERTIFIER® semi-portable wind tunnels have a small test section ideal for flow measurements on small devices or for air velocity sensor testing/analysis and test instrument calibration.
