Sonic SAT-900 Ultrasonic 3-D Strong Wind Anemometer

SAT-900 observation purpose for the local strong wind disaster and to the low layer weather and local meteorological observation. 3-D Strong wind can measurement up to 90m/s evaluation by its wind tunnel equipment.


  • Adopting a new sensor, a strong wind can be measured.
  • Data with high reliability in strong wind is possible, thanks to new digital processing DSP.
  • Measurement from 0 m/s to 90 m/s with high response and linearity.
  • 3-D measurement of horizontal and vertical wind speed(blowing up and down) is possible.
  • Without moving part, free from damage under the strong wind condition.
