Measuring the wind is essential for the wind energy industry. Anemometers are the key instruments for wind speed measurement. In order to evaluate the accuracy and stability of anemometers, each sensor is individually calibrated in a wind tunnel. Ammonit Wind Tunnel GmbH (AWT) has designed and built its own wind tunnel to offer top-quality calibration services.

In order to measure wind conditions as precisely as possible, top quality and calibrated measurement instruments are crucial. Non-calibrated sensors can significantly increase the uncertainty factor for planning and implementing wind energy projects as well as for technical surveying of wind turbines.

Ammonit Wind Tunnel is accredited by DAkkS as independent calibration laboratory according to DIN EN ISO / IEC 17025. We are member of the MEASNET group. Our wind tunnel has been verified and meets the high quality criteria of MEASNET for sensor calibration. Hence, we calibrate your sensors in our wind tunnel according to IEC 61400-12-1 and MEASNET.

Ammonit Wind Tunnel GmbH has been founded by Ammonit Measurement GmbH and WIND-consult GmbH to pool competences in the field of flow measurement and meteorological measurement technology.

Ammonit Wind Tunnel is headquartered in Bargeshagen near Rostock on the coast of the Baltic Sea. The company operates a wind tunnel for wind sensor calibration and testing. The wind tunnel design allows even calibrating large sensors, such as ultrasonic anemometers.

• Total area covered: 144 m² (approx. 18 m x approx. 7 m) 

• Total length: 50 m (18 + 7 + 18 + 7) 

• Nozzle cross section: 1.20 x 1.20 m 

• Length of working section: 2 m 

• Contraction ratio: 9 : 1 

• Turbulence intensity: < 0.2% 

• Max. wind speed: 30 m/s 

• Capacity: 40 kW

With the new wind tunnel we extend our services for sensor calibration. Hence, you benefit from very good prices and fast logistics. Each calibrated sensor comes with a detailed calibration certificate. In the near future, calibration certificates can be downloaded via the website of Ammonit Wind Tunnel: https://ammonit-windtunnel.com
