High quality, general purpose, ultrasonic anemometers
Gill WindSonic 75 (MTI.AWS.GL.WS75) is a low-cost, high speed anemometer, which utilises Gill’s proven ultrasonic technology to provide wind speed and direction data via one serial or two analogue outputs. To confirm correct operation, outputs are transmitted together with an instrument status code. WindSonic is WMO-compliant for gust measurement.
With a robust, corrosion-free polycarbonate housing, this small, lightweight wind sensor is recommended for use in harsh environmental conditions and is particularly suited to marine & offshore (ships, data buoys) and land based installations. WindSonic anemometers have no moving parts, offering maintenance-free operation in a wide range of applications
