Compare 2 Axis Anemometers
Gill offers three ranges of 2-axis anemometers (sometimes referred to as 2D anemometers): WindSonic, WindUltra 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.
WindUltra Range – extremely tough, compact and lightweight, high performance 2-axis ultrasonic anemometers
WindUltra anemometers are more compact and lightweight than the WindSonic range and offer innovative mounting features for quick installation and alignment. The range is suitable for most applications and comes with a range of output formats. WindUltra incorporates a reflector design and has low power consumption heating as standard.
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.
