Today, modern measurement technologies enable high-precision detection of the movement of liquids and gases, providing valuable data for numerous applications. How does air flow around an airplane? How does blood move through our veins? And how can pollutant emissions in combustion processes be minimized? For these and other purposes, speed, direction, pressure, and turbulence within a flow are analyzed to increase efficiency, ensure safety, and drive innovation in numerous areas.

Various methods are available to measure these flows, including visual ones such as particle image velocimetry (PIV). High-resolution cameras are used to track marked particles within a flow and analyze their movement. iLA_5150 GmbH, from Aachen, Germany, also relies on EBIV (event-based particle image velocimetry). It’s a new optical method for the qualitative and quantitative visualization of flows and flow velocities. It combines PIV with event-based cameras, in this case with a uEye EVS from IDS Imaging Development Systems. The innovative sensor technology of this industrial camera enables highly dynamic and energy-efficient detection, especially for fast and turbulent movements.
