Deutsche WindGuard Wind Tunnel Services increases service scope, reduces measurement uncertainty

Quality improvements and new certifications in all four calibration wind tunnels

Varel, 2020-04-28: Leading wind tunnel specialist Deutsche WindGuard has extended the DAkkS-accredited measurement range. Accredited anemometer calibrations can now be conducted with flow speeds from 0.5 m/s up to 38 m/s. In the same course, the overall measurement uncertainty was reduced to 0.25 % (however not less than 0.025 m/s). This is the result of a long-term internal quality initiative. During said initiative, the fourth calibration wind tunnel with a test section area of 1.2 m by 1.2 m received MEASNET approval.

"As part of our commitment to the highest quality, we have succeeded in reducing the measurement uncertainty by up to 60 % in a sustainable manner," says Nicholas Balaresque, Managing Director of Deutsche WindGuard Wind Tunnel Services GmbH. "These extremely precise measurements were made possible by a comprehensive improvement process and state-of-the-art measurement technology. Among other things, we use the Laser Doppler-Anemometer (LDA) in one of our four wind tunnels, which Germany’s National Metrology Institute, the PTB, uses as the primary standard for wind velocity."
