Information About an Anemometer

An anemometer is a tool used to measure the velocity and pressure of the wind. There are many types of anemometers, some of which date back as far as 1450.


The first anemometers were created during the 15th century in Italy, where Leonardo da Vinci and Leon Battista Alberti each devised plans for a device that measured wind pressure. The first modern anemometer was created by Thomas Romney Robinson in 1850.


The word "anemometer" comes from the Greek word for wind, "anemos."


There are two main types of anemometers, those that measure wind speed or velocity and those that measure wind pressure.


Velocity anemometers may use the rotation speed of windmills or cups on spokes to measure wind speed. Pressure anemometers can measure how much force is exerted on a metal plate or how much the force of wind displaces liquid in an enclosed glass tube.


Anemometers are sometimes free-standing individual tools, or they can be included in a weather station that also measures temperature and humidity.
