The WindSonic1-ETM is a two-dimensional ultrasonic anemometer for measuring wind speed and direction. On this version of the WindSonic1, the cable is fitted with a connector and has the ideal length for attachment to the ET107 Station. The WindSonic1-ETM includes a 1.2 ft pipe that can be used with the ET107’s crossarm U-bolt bracket.
WindSonics are manufactured by Gill Instruments Ltd.
The WindSonic1 uses two pairs of orthogonally oriented transducers to sense the horizontal wind. The transducers bounce the ultrasonic signal from a hood, thus minimizing the effects of transducer shadowing and flow distortion.
Unlike mechanical anemometers, the WindSonic1 has no moving parts to be periodically replaced—minimizing routine maintenance costs.
