The WindMaster RA (right angled) 3D sonic anemometer offers an alternative head design where an omni-directional measurement concept is desired while minimising any mechanical influence in the vertical wind plane to provide users with the least disturbed wind measurement for non-stationary measurement applications with a known predominant wind direction.
