UVP software

UVP SOFTWARE A completely new software package - version 3 - has been developped for the new instrument generation UVP-DUO. It has been programmed from scratch with Win32 standards, featuring both data acquisition and post-processing in a single core program. It is a powerful software capable of handling large quantity of data as delivered by the new hardware performances, and this as well under old Windows 98 as on the latest Windows XP Pro operating systems. In addition version 3 software has been adapted to Windows NT kernel to allow UVP-XW users of the former standard version 2.1 to upgrade. New features... Parameters settings... Real-time computation... Post-processing... Software upgrades and updates...

top NEW FEATURES AND IMPROVEMENTS IN VERSION 3 SOFTWARE Selectable number of channels in profile from 10 to 2048 (256 for UVP-XW) Remote control of UVP-DUO or UVP-XW from a host computer via a LAN network Turbulent statistics, RMS, skewness, kurtosis, histograms Cross-correlation, auto-correlation, power spectrum Integrated flow mapping module (2D measurement), on-line transducer grid editor New file format with complete integrated description header Compatibility with former UVP file format Compatibility with third-party software: Clipboard function, export to Word, Excel, Tecplot Compatibility with any MS Windows operating system from Windows 98 Perfect standard Win32 interface Minimum PC hardware requirements as necessary to run the installed operating system
top PARAMETERS SETTINGS The use of the whole program is very intuitive and follows Microsoft guidelines for interface design. Great care has been taken to make version 3 as user-friendly as possible. A wizard-style dialog allows for easy setting of UVP parameters, checking settings consistency and suggesting suitable ranges when required, using visuals aids for some specific data. Parameters are recorded in each UVP file header; to retrieve the settings of any UVP measurement you simply open its data file to load the corresponding parameters.
top REAL-TIME COMPUTATION The velocity calculation from Doppler-shift detection is being made real-time by the Digital Signal Processor inside the UVP device. UVP version 3 program can then display velocity profile real-time while storing the corresponding data. All data displays have context-sensitive options that can be modified by right mouse button click; cursor coordinates are continuously displayed; display zooming and moving is possible at any time, and specific data point displays can be called by selection directly on the graph.
Time series from single velocity channel at a fixed distance can be monitored real-time. Sets of time series from various channels can be displayed in parallel, moreover smoothing filter can be applied and modified real-time without losing the raw velocity data.
Raw echo amplitude as a function of distance can be displayed real-time in parallel with velovity profile, with the same distance scale. It is very useful for correlating the raw echographic information with calculated velocity, and check for possible strong static reflection that could spoil the velocity processing. In some specific cases it allows to display flow boundaries like walls, obstacles, etc...
top POST-PROCESSING Various types of analysis and post-processing can be achieved offline on the velocity data. Software version 3 offers different kind of statistical tools like velocity histogram (picture at right), statistical moments, etc... to analyze turbulence.
Power spectrum function (picture at right) analyses frequency distribution of turbulent energy in the flow. Moreover cross- and auto correlation analyses periodicities and relationships between different points in time and space.
A complete flow mapping module is integrated in software version 3. It allows for 2D velocity measurements by calculating the velocity field at the crossing points of a transducers grid, each probe being connected to the instrument internal multiplexer. This module includes among other things a transducer position editing table and display (picture at right), a flow mapping sequence editor and an multiplexer channels test facility for each transducer.
The flow mapping module also includes 2D velocity field table and display (picture at right), movie tool to animate the velocity field as a function of time, export utility to external program such as Tecplot or Excel.
top SOFTWARE UPGRADES AND UPDATES UVP-DUO Software version 3 is installed on the distant computer controlling the instrument. It can be run on either Windows 98, ME, SE, NT4, 2000, XP Home/Pro, the minimum hardware system requirements being as necessary to run the installed operating system. Software version 3 is regularly updated, and UVP-DUO users are advised accordingly. UVP-XW UVP-XW standard operating software is version 2.1 (available at no cost for any UVP-XW user), installed on the UVP-XW internal PC running on Windows NT4. Nevertheless version 3 has been adapted for Windows NT4 drivers and is now available for UVP-XW users. Please contact your local agent for any further informations Software 3 demo version A demo version of software version 3 running on any PC is available for evaluation, please contact your local agent or Met-Flow for more information.
