风速计是一种测量风速的仪器。通常分为风叶型（风车型）和风杯型。气象站使用的是风杯型的，一般安装在离地10米高的杆子上，四周应空旷。根据一定时间内风杯的转速，可算出平均速度。

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed measurement instrument used in meteorology . The first known description of an anemometer was given by Leon Battista Alberti in 1450.
