V3V-Flex Volumetric PIV Systems

Request A Quote Required Components

In conjunction with the 3-camera V3V 9000 framed based volumetric PIV system, TSI's latest V3V-Flex volumetric PIV system, with enhanced spatial and temporal resolution, meets the increasingly challenging requirements for fluid flow research in air and liquid. Its flexibility arrangement allows different camera configurations to achieve the optimal measurement volume and spatial resolution required for your measurements.

Product Details

Whether the system is configured with high-speed cameras for time-resolved measurement with high temporal resolution, or is equipped with high-pixel resolution cameras for the exploration of ultra fine structure of the flow field, this system can provide users with 3D3C results quickly and accurately.  The capabilities of the new V3V-Flex volumetric PIV system are designed to meet your most challenging flow measurement requirements.

Based on the Tomographic Aperture-Encoded Particle Tracking Velocimetry (TAPTV) technique, both V3V and V3V-Flex systems offer the most powerful and robust arrangement for the 3D3C and Time-Resolved 3D3C measurements in fluid flows.


  • Flexible camera configurations for the multiple camera arrangement, for optimal measurement volume size of over hundreds of mm 3 and velocity spacing less than 1 mm.
  • Multiple camera support from 2 to 8 cameras
  • Variety of hardware allows users to choose between high-temporal or spatial resolution, or both
  • High-temporal resolution with image capture from 1kHz to 50kHz capture rates, giving time-resolved capability (4D) for tracking unsteady flows
  • High resolution cameras of 1MP to 29MP with frame rate from 1Hz to 200Hz
  • Individual Scheimpflug mount arrangement on all the cameras for the best focus of particles in the 3D volume
  • PIV, Stereo PIV and V3V Systems are expandable to the V3V-Flex system, with the same camera hardware and calibration system


  • Turbulent boundary layers
  • Fluid/structure interaction
  • Internal flows
  • Biological flows

Please refer to the system brochure and specification sheet for more details on the system.
