APPLICATIONS
The Scintec XFAS is a high-performance, long-range acoustic profiler for
the measurement of wind and turbulence within the atmospheric boundary
layer.
The operation is based on the reflection of acoustic pulses at temperature
inhomogeneities in the air with subsequent doppler analysis.
The instrument can replace towers,
tethered balloons or radiosondes at a
fraction of the operational costs. The
system can be easily transported and
installed. Low power consumption
facilitates operation in remote areas.
With its proprietary Flat Array Antenna
and patented technology, the Scintec
XFAS has significant advantages in
accuracy, data availability, energy
efficiency, lifetime and serviceability
– even over systems which are much
larger and require more power.
The versatile but easy-to-use operation software APRun satisfies the most
demanding needs. Its configurability,
graphical display and output options,
quality control features, statistical
analysis tools, remote access support
and self-test functions define today’s
standard in wind profiler operation
software.
