Overview
The WindSonic4-QD is a two-dimensional ultrasonic anemometer for measuring wind speed and direction. 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.
WindSonics are manufactured by Gill Instruments Ltd.
Read MoreThe "-QD" version of this product has a cable that terminates in a military style connector (instead of pigtails) and is the ideal length for attachment to a RAWS-F Fire Weather Quick Deployment Station.

Detailed 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.
