| Summary: | For problems of manual adjustment of wind volume many times, complex operation, large time and laborious consumption of manual data reading and drawing and low calibration precision existed in traditional calibration methods of wind meter, a wind tunnel test device for automatic calibration of multiple wind meters was designed and structure and test principle of the device were introduced. The test result shows that the device can automatically adjust wind volume with steady wind by simple operation, calibrate multiple wind meters at a time with high calibration precision, and record, store and process calibration results, which is suitable for automatic calibration of low, medium and high grade wind meters.
