3-Axis Right Angled Ultrasonic Anemometer
The Gill WindMaster RA (MTI.AWS.GL.RA) is a right angled precision anemometer offering three-axis measurement data. This instrument will monitor wind speeds of 0-50m/s and provides sonic temperature, speed of sound and U, V & W vector outputs at 20Hz (32Hz optional)
This anemometer is of aluminium/carbon fibre construction and is ideal for the understanding of turbulent flows, surface energy balance and scalar fluxes. Each WindMaster3 can be calibrated with an optional Gill wind tunnel test to provide optimum performance.
This 3D sonic anemometer is ideally suited to the measurement of air turbulence around bridges, buildings, wind turbine sites, building ventilation control systems, meteorological and flux measurement sites.
