3-Axis Ultrasonic Anemometer
WindMaster 3-axis ultrasonic anemometers are used to gather high value information by a range of customers. Users include wind energy site surveyors, military engineers and research scientists. WindMaster has also been selected by a number of global OEMs and system integrators as a core sensor within their systems.
Models are also available with a horizontal head design for highly accurate vertical flow analysis or right-angled head design for restricted installation scenarios.
The Gill WindMaster is a precision anemometer offering three-axis wind 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 WindMaster 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.
