The TSI Models FM-1000 and FM-1100 Quantitative Flow Visualization Systems, provide a turn-key solution to investigate quickly and accurately the flow field for your applications. The system is non-intrusive and offers high spatial and temporal resolution as well as the ability to resolve turbulence structures.



The FM-1000/1100 system is an easy set up for flow investigations. Once the camera is focused on particles on the laser light sheet, flow information is captured and analyzed, giving instantaneous velocity field results for that particular plane.

Capturing a sequence of images provides useful statistical information such as average velocities field, vorticities, and shear, as well as time-animations; providing detailed information regarding vortex trajectories and evolving regions of high and low velocity.

Both the FM-1000 and FM-1100 share the same system components: laser, camera, synchronizer and software. The exception is the BG-1000 bubble generator,which is designed for air flow applications. Therefore, the FM-1000 system with the BG-1000 bubble generator included is catered for air flow applications, while the FM-1100 is a system ideal for water flow measurements.
