Particle Image Velocimetry (PIV) is a whole-flow-field technique providing instantaneous velocity vector measurements in a cross-section of a flow.
 
Features:
• The technique is non-intrusive and measures the velocities of micron-sized particles following the flow.

• Velocity range from zero to supersonic.

• Instantaneous velocity vector maps in a cross-section of the flow.

• All three components may be obtained with the use of a stereoscopic arrangement.

• With sequences of velocity vector maps, statistics, spatial correlations and other relevant data are available.
