A wind cup anemometer is a commonly used wind measurement instrument in meteorological observation, environmental monitoring, and aerospace. It has broad application prospects in industrial production and other fields. Its accurate measurement is of great significance for research and applications in weather forecasting, climate research, aviation and navigation, and other fields.
Anemometer basic
The cup anemometer is an instrument for measuring air flow velocity. Its sensing part consists of three parabolic cones fixed on the bracket at 120 degrees to each other.
It is composed of cups, and the concave surfaces of the empty cups all face one direction. The entire sensing part is installed on a vertical rotating axis. Under the influence of wind force, the wind cup rotates around the axis at a speed proportional to the wind speed. Cup anemometers have the advantages of large wind measurement range, high strength, and corrosion resistance, and are widely used in meteorological stations.
Therefore, the function of the cup anemometer is to measure wind speed, and its sensing part can measure the magnitude and direction of the average wind speed. Its working principle is to use wind power to drive the wind cup to rotate around its axis. The rotation speed is proportional to the wind speed. The wind speed is calculated by measuring the rotation speed.

By measuring airflow velocity, ventilation and heat dissipation in farmland can be assessed, as well as preventing and controlling the spread of pests and diseases.
Importance of anemometer
The sensing part consists of three parabolic cone empty cups fixed on the bracket at 120° to each other. The concave surfaces of the empty cups are all oriented in one direction. The entire sensing part is installed on a vertical rotating axis. Under the action of wind force, the wind cup rotates around the axis at a speed proportional to the wind speed. In addition, by using flow field simulation software, the movement of the wind cup in the atmosphere can be simulated. By changing the structural parameters of the wind cup, the movement characteristics of the wind cup with different structural parameters in the atmosphere can be simulated, and the structure can be analyzed based on the results. The influence of parameters on the dynamic and static characteristics of the wind cup.
