LaVision’s ParticleMaster system family is designed to simultaneously determine size and velocity of individual particles or droplets in fluids or multiphase flows. The imaging systems analyze various types of particle laden fluids and other two-phase flows with high spatial resolution. Data acquisition and on-line evaluation are performed with the versatile DaVis software.
