WindMaster - 3 Axis Ultrasonic Anemometer

show your currency

The new WindMaster three axis anemometer is a robust 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 WindMaster is available with a 20Hz data output rate with an option to increase this to 32Hz. The instrument is constructed in the familiar Aluminium/carbon fibre construction. Both software and electronics have been enhanced to provide improved vertical (W) resolution and SOS accuracy.

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.
