[0002] An anemometer is a test instrument that converts flow velocity signals into electrical signals and measures air velocity. There are many types of anemometers, such as cup anemometers, propeller anemometers, hot wire anemometers, digital anemometers, and acoustic anemometers. Regardless of the type of anemometer, its measurement accuracy needs to be tested before it is put into use to ensure the measurement accuracy of the anemometer. This is a detection device for detecting anemometers.

[0003] The commonly used detection method is: place the anemometer in the pipeline, use the exhaust fan to form airflow in the pipeline, use the atmospheric pressure gauge to detect the air pressure value in the pipeline, the anemometer detects the wind speed of the airflow in the pipeline to obtain wind speed data, and uses the pitot tube anemometer to detect the wind speed in the pipeline as a data standard, and compares the wind speed data of the anemometer with the standard wind speed data of the airflow in the pipeline, so as to detect the test accuracy of the anemometer. However, the current problems in using the airflow pipeline for detection are: the pipeline is a straight pipeline, the air inlet of the pipeline will produce a high-speed airflow area, the inside of the pipeline is a low-speed area, and the airflow distribution in the pipeline is uneven, which causes detection errors and reduces the accuracy of the anemometer detection device.
