PIV
Enlarge Image+

Particle image velocimetry (PIV) systems measure the instantaneous global velocity field in a flowing fluid. Since introducing the first commercial PIV system in 1988, TSI has led the way in PIV innovation and technology. Our 2D PIV system maintains this tradition by incorporating the most advanced analysis schemes in a completely re-engineered software platform built for flexibility and expansion. Features such as grid deformation, the patented Hart and Rohaly-Hart correlation algorithms, and other algorithms from our exclusive license to MicroPIV technology such as ensemble correlation averaging and background correction, ensure the highest possible measurement accuracy even in sparsely seeded flows and flows with large spatial velocity gradients.

Traverse Accessories for PIV - Traverse Accessories for PIV

Traverse accessories help the user get the most productivity out of their TSI traverse while enhancing operating safety. Casters permit the traverse to be easily moved from place to place, increasing the versatility of the PIV system. Foundation brackets rigidly attach the base frame to the floor to prevent tipping when floor is uneven, in earthquake-prone areas, or when the traverse is unevenly loaded.

Synchronizer - 610034

  • External trigger option for phase-locked velocity measurements
  • Automates control of laser pulses, cameras, and timing to external signals
