Functional Description
The Vectrino velocimeter
operating principle:
A pulse
is transmitted from the centre
transducer, and the Doppler
shift introduced by the
reflections from particles
suspended in the water, is
picked up by the four
receivers.
Data Handling
The Vectrino software saves data in binary files, which are easily converted
to ASCII format files, using the conversion module in the software.
• The *.hdr file is a self-documented table. Please note that this file
contains a detailed data format description of all files that are
generated.
• The *.dat file contains velocity data at the full sample rate.
ASCII files are easily imported into most spreadsheets and data analysis
programs. For turbulent data analysis, Nortek recommends the use of a
specially developed program, ExploreV. You can learn more about this
program on our web pages: Go to
