WindMaster Pro - 3 Axis Ultrasonic Anemometer

show your currency

The new WindMaster Pro three axis anemometer is a robust stainless steel instrument based on time of flight measurements and is essential in the understanding of turbulent flows, surface energy balance and scalar fluxes.

Gill employs the optimum mechanical configuration and electronic processing to minimise flow distortion and transducer shadow effects. The WindMasterPro is fitted with field proven standard Gill transducers with the ability to measure a top wind speed of 65 m/s.

The elegant design has been developed to provide improved vertical (W) resolution, SOS accuracy and less distortion due to wind loading. New design electronics has facilitated a reduction in power consumption to 30 mA at 12 V dc, a significant advantage when used on power sensitive sites.
