Thies Clima - Model 4.383x.2x.xxx -3D Ultrasonic Anemometer
The Ultrasonic Anemometer 3D serves for the 3-dimensional acquisition of the horizontal and vertical components of the wind velocity, the wind direction as well as of the acoustic-virtual temperature. The ultrasonic measurement principle allows, compared to the classic anemometers, an inertia-free measurement of running variable dimensions with highest precision and accuracy. It is especially suitable for the measurement of gust- and peak values.
Heated components:
- sensor arms
- ultrasonic transducers
More than 70 different measurement values are available, for ex.:
- Wind velocity in X/Y/Z-direction
- Total wind velocity
- Wind velocity azimuth
- Wind direction azimuth
- Wind velocity elevation
- Wind direction elevation
- Acoustic-virtual temperature
- Standard deviation of the wind velocity in X/Y/Z-direction
- Standard deviation of the total wind velocity
- Standard deviation of the wind velocity azimuth
- Standard deviation of the wind direction azimuth
- Standard deviation of the wind direction elevation
- Standard deviation of the acoustic-virtual temperature
- Statistic functions such as variance, co-variance, turbulence intensity
- Wind velocity X/Y/Z of the gust acc. to WMO
- Wind direction of the gust (elevation) acc. to WMO
The instrument is especially suitable for the use in the fields of
- Meteorology
- Climatology
- Traffic engineering, aviation and navigation
- Indoor flow measurement
- And in alpine field of application
