    Abstract:
    In order to solve the problem that there is no verification and calibration capability for wind speed sensors above 70 m/s in China, this paper designs a wind tunnel with the 90 m/s upper limit of wind speed. The moving guide rail makes the test section with open/close dualpurpose. The overall size of the wind tunnel is 26 m×10 m×4.2 m (length, width and height). The velocity range is 0.4 to 90.74 m/s. The control system adopts the fully digital design of physical quantity to meet the automatic demand of metrological experiments. The performance indicators have passed the acceptance test, which means that the tunnel fulfills the test specification for meteorological low speed wind tunnel performance.
