An anemometer is a device that is used to measure the speed of the wind in a given place.  The reason that the word does not sound like it has anything to do with wind is because the instrument's name is derived from a Greek word for "wind."  The word literally means "wind measurer."

The first anemometer that is known was invented in 1450.  The inventor was an Italian by the name of Leon Battista Alberti.  The type of anemometer most used today was invented in 1846 by an Irishman named John Thomas Romney Robinson.

it is used to measure the wind speed . it has got four cups and when the wind blows the cups rotates . we can calculate the wind speed by knowing the number of rotation caused in particular time time and by dividing both we will get the wind speed .

An anemometer is a device for measuring wind speed, and is a common weather station instrument

Anemometers can be divided into two classes: those that measure the wind's speed, and those that measure the wind's pressure; but as there is a close connection between the pressure and the speed, an anemometer designed for one will give information about both.
