WindGuard the First to be Accredited for the Calibration of Wind Vanes Worldwide

- Deutsche WindGuard Wind Tunnel Services is the first company to be accredited by DAkkS (national accreditation body of Germany) for the calibration of wind vanes


Varel - Deutsche WindGuard Wind Tunnel Services is now accredited by DAkkS for the calibration of wind vanes according to DIN EN ISO/IEC 17025:2005. This comes in addition to the already existing accreditation for the calibration of anemometers. WindGuard is the first company worldwide to hold such an official approval.

For accredited measurements, such as power curve measurements on wind turbines, all deployed sensors have to be calibrated, including wind direction sensors. Only that there was no vendor for this kind of calibration on the market - until now! \"Historically, the importance of wind vane calibration has been underestimated,\" says Dieter Westermann, managing director of Deutsche WindGuard Wind Tunnel Services, \"even though we depend on the high accuracy of wind vanes in many areas. The calculation of flow models, for example or the planning of wind farm layouts. Also, turbines need a wind vane signal so that they can align themselves into the wind. With an inaccurate signal, the alignment will be inaccurate, resulting in an inevitable loss in energy output.\"

Dr. Knud Rehfeldt, managing director of Deutsche WindGuard, adds: \"We are very proud to be the first to take this important step in raising the overall accuracy of wind measurements, benefitting the entire wind energy industry.\"

The Wind Tunnel Center of Deutsche WindGuard can guarantee the highest calibration accuracies with an uncertainty of 0.8° (k=2).
Deutsche WindGuard offers its customers engineering services of the highest standards in all areas of wind energy utilisation. WindGuard combines years of practical experience and scientific know-how in all areas of wind energy utilisation- ranging from site assessment issues via technical management of wind farms to the complete surveying of wind turbines.
