An anemometer is a meteorological instrument used to measure wind speed, temperature and humidity. It also calculates and displays dewpoint and wind chill factor. It is essential for monitoring the environment. It can be divided into two classes: one that measures the velocity of the wind, and another one that measures pressure of the wind.
An anemometer is a device for measuring the velocity or the pressure of the wind, and is one instrument used in a weather station. Anemometer can be divided into two classes: those that measure the velocity of the wind, and those that measure the pressure of the wind, but as there is a close connection between the pressure and the velocity and a suitable anemometer of either class can give information about both these quantities.
