3-Axis Ultrasonic Anemometer

3-Axis Ultrasonic Anemometer



Order

Description

A precision three-axis wind measurement anemometer, the WindMaster monitors wind speeds of 0 45 m/s and provides sonic temperature, speed of sound and U, V & W vector outputs at 20Hz (32Hz optional).


Feature

  • Aluminum/carbon fiber construction
  • Ideal for the study of turbulent flows, surface energy balance and scalar fluxes
  • Calibrated with a wind tunnel test to provide optimum performance
  • Ideally suited to the measurement of air turbulence around bridges, buildings, wind turbine sites, building ventilation control systems, meteorological and flux measurement sites.
  • 0 to 3590 wind direction
  • 0-45m/s wind speed
  • Sonic Temperature Output
  • Precision 3-axis sonic anemometer
  • U, V, W vector outputs
  • 20Hz output rate
  • Optional Custom Calibration
