Answer
Anemometer
Explanation
An anemometer is a device used for measuring wind speed and direction. It is a common weather station instrument. The term is derived from the Greek word 'anemos', which means wind. The most common type is the cup anemometer, which has cups that catch the wind and spin to calculate speed.
Key Points
- > Anemometer measures wind velocity/speed.
- > Barometer measures atmospheric pressure.
- > Manometer measures fluid pressure in closed systems.
- > Thermometer measures temperature.
- > Hygrometer measures humidity in the air.
- > Wind Vane (or weather vane) shows the direction of the wind.
- > Derived from the Greek word 'anemos' meaning wind.
