WINDSONIC4-QD 2-D Sonic Wind Sensor with SDI-12 Output for RAWS-F Stations

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.

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.

Sensor Mounts

The WindSonic is mounted to the RAWS-F via the 17387 Mounting Pipe Kit. This kit is shipped with the WindSonic4-QD and RAWS-F. The 17387 is also offered as a replacement item (see Ordering Info tab for more information).
