This highly compact miniLDV system is a great complement to FLOWCOACH where PIV & LDV can be utilized to provide students a complete understanding and demonstration of flow phenomena including turbulence measurements. The miniLDV System is an optional add on to FLOWCOACH. Simply attach the probe to the articulated arm in front of FLOWCOACH. The Burst Processor software collects data, moves the probe on the optional electronic traverses, and presents flow statistics such as flow velocities and turbulence. The process of measuring a profile is fully automated. The user simply dictates how many points per station to take, and the software does the rest. Please note that the Burst Processor software is not integrated into FLOWEX software.

The miniLDV System consists of:

Mini LDV probe,
Signal Processor,
1D Burst Processor Acquisition Manager software package.

Optionally available are linear traversing systems (one or two axes) with manual or electronic drive (electronic traverses are controlled from within the software) and a computer with the software installed and verified by our technicians. The miniLDV probe is also available with an integrated Processing Engine as the Integrated miniLDV. 2D & 3D versions are also available. If the standard probes do not suit your needs, feel free to contact us and inquire about custom solutions.
