[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine with an exhaust pressure lower than 1.5×10^4 Pa. Modern fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air intake of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0003] The air volume and speed of the ventilator need to be measured during the production process, so an air volume and speed testing device (wind speed meter) is needed to control the parameters of the ventilator and ensure the pass rate of each ventilator before leaving the factory.

[0004] However, when testing the ventilator with the existing wind volume and wind speed testing device, the worker needs to hold the wind volume and wind speed testing device in hand to test the ventilator. Although this testing method can measure the wind of the ventilator, due to the instability of the handheld wind volume and wind speed testing device, the measured values ​​will have a certain deviation. Moreover, when performing multi-point wind measurement on the ventilator, the worker's hand holding the wind volume and wind speed testing device for a long time will cause the worker's hand to become weak, thereby affecting the wind measurement data.
