We perform cup anemometer classifications following the procedure of IEC 61400-12-1:2017.

We also perform ASTM tests of anemometers and vanes according to ASTM D5096 Standard Test Method for Determining the Performance of a Cup Anemometer or Propeller Anemometer and ASTM D5366 Standard Test Method for Determining the Dynamic Performance of a Wind Vane, respectively.

Some of our experimental procedures have been developed in collaboration with DTU Wind Energy (Technical University of Denmark). Below is a list of possible tests:

• Rotor torque characteristic
• Bearing friction at temperatures -20 to 40 deg. C.
• Tilt response
• Yaw sensitivity
• Threshold
• Distance constant

Furthermore, the classification includes:

• Numerical simulation of anemometer response using software verified by DTU and compliant with the requirements of IEC 61400-12-1:2017, Annex J.
• Full documentation of tests and reporting final class indices for classes A, B, C and D.

If you have any special requests, we have the expertise to handle it!
