Technical Description

The WindSonic4 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.

The WindSonic4-QD outputs an SDI-12 signal that is read by the RAWS-F's on-board CR1000M module. This sensor provides an alternative to the 034B-QD, a traditional mechanical cup and vane anemometer. Unlike mechanical anemometers, there are no moving parts to be periodically replaced—minimizing routine maintenance costs.
