Ultrasonic Anemometer
The Gill WindObserver II ( MTI.AWS.GL.WOII) is a precision, solid-state ultrasonic anemometer which has been type approved by the Lloyds Register for use in marine and offshore applications. The WindObserver II provides wind speed and direction data via 1 digital and 3 analogue outputs and features and IP66 rated stainless steel housing, which is particularly suitable for use in salt-water environments.
Offering a high wind speed measurement range, this anemometer has an optional de-icing system enabling the sensor to operate effectively in environmental conditions experienced at high altitude or at sea and is recommended for use in aviation, marine and offshore applications.
Customer selectable vector rolling average and 3 second gust in accordance with WMO - No. 8 Seventh Edition 2008 ISBN 978-92-63-10008-5.
