Compare 2 Axis Anemometers
Gill offers two ranges of 2-axis anemometers (sometimes referred to as 2D anemometers): WindSonic and WindObserver.
WindSonic Range – cost effective, high performance 2-axis ultrasonic anemometers
The WindSonic range consists of high quality, multi-purpose anemometers. The range is suitable for most applications, is available in a range of materials for different environments and with a range of output formats. The product incorporates a reflector design and is available with or without heating.
WindObserver Range – precision 2-axis ultrasonic anemometers for demanding applications
The WindObserver range is based on an open head design. This allows for higher wind speed measurement and greater accuracy when the angle of wind flow is increased. With higher output rates, a range of output formats and a robust stainless steel design, the range is popular for specialist applications such as marine, airport and wind power generation.
