Gill Company in the UK has been producing ultrasonic airflow measurement systems for over 20 years, which are widely used in ultrasonic wind speed and direction systems. The robust and stable structure makes these products almost maintenance free, making them suitable for various environments.

WindMaster (Pro) is a high-performance 3D ultrasonic anemometer produced by Gill, which is essential for turbulence, energy balance, and gradient flux research. It has been widely used in professional meteorological observation systems, road meteorological stations, building safety wind tests, wind power generation research, ocean wind research, flux systems, and many other fields.

WindMaster is the basic model of this series of products, and WindMaster Pro has more outstanding design performance, which can provide users with more accurate measurement data in a larger measurement range.

R3-50 is a high-performance, high reliability, and low-cost 3D ultrasonic anemometer developed by Gill Company using industry-leading technology and years of industry experience. It can operate normally under complex and harsh weather conditions.

The design of HS-50 three-dimensional ultrasonic anemometer meets the scientific research requirements for accurate three-dimensional wind speed, wind direction, and ultrasonic temperature measurement data. The advanced ultrasonic measurement technology and unique transverse measuring head design are adopted, which enables the ultrasonic anemometer to minimize the interference of the instrument's physical structure on the airflow when measuring at high angles of attack.

The unique design of Gill ultrasonic anemometer minimizes interference with airflow and reduces the shadow effect of the sensor to the greatest extent possible. Each ultrasonic anemometer undergoes wind tunnel testing and calibration before leaving the factory to achieve excellent performance.
