The FlexPDA system is designed to deliver a complete entry-level PDA/LDA platform for particle size and velocity measurement. The system can be configured for 1D or 2D velocity measurements, and integrated with a 1D, 2D, or 3D traversing units for spatial mapping.

PDA (Particle Dynamics Analyzer) – also known as PDPA (Phase Doppler Particle Analyzer) and PDI (Phase Doppler Interferometer) – is a well-established technique for the simultaneous measurement of particle size and velocity. PDA works as an extension to Laser Doppler Anemometry (LDA), both are optical techniques ideal for non-intrusive point measurement in a wide range of fluid dynamics applications.

The FlexPDA solution inherits the best of PDA and LDA technology, resulting in a compact best-value system for simultaneous particle size and velocity measurement applications.
