Cup anemometers function is to measure wind speed. Specifically, cup anemometers use cups (usually three) to measure the speed of the wind. The cups rotate at a speed proportional to the wind speed. This rotation is measured by a sensor that converts it into an electrical signal, which can then be interpreted to determine the wind speed.

Cup anemometers are commonly used in meteorology and environmental monitoring to measure wind speed and direction. They are also used in aviation and marine weather forecasting, among other applications.

The cups of the cup anemometer are made of a light-weight material that allows them to rotate easily in high winds. The sensor inside the anemometer measures the rotation of the cups and converts it into an electrical signal. This signal is then processed by the instrument to determine the wind speed and direction.

The cup anemometer has the following functions:

Measuring wind speed: Cup anemometers can measure the magnitude of wind speed to help people understand the changes in wind speed.

Measuring wind direction: Some cup anemometers also have the function of measuring wind direction, which can measure wind direction and wind speed at the same time, providing more comprehensive data for meteorological observation and environmental monitoring.

Measuring average wind speed: Some cup anemometers can measure the average wind speed over a period of time to help people understand the average wind speed.

Measurement of Instantaneous Wind Levels: Some cup anemometers can also measure instantaneous wind levels to help people understand how the wind is changing.

Measurement of Wave Height: Some cup anemometers can also measure wave height to help people understand how the waves are doing.

Some portable cup anemometers usually have small size and weight, which are easy to carry and use. It can measure wind speed anytime and anywhere, which is very suitable for fieldwork, emergency rescue and other fields.

Cup anemometers are usually battery-powered and can be handheld or fixed to a mast or other structure. They are designed to be durable and accurate even in extreme weather conditions.
