An anemometer is an instrument used to measure wind speed and sometimes direction. First developed in the 15th century, anemometers have evolved from simple mechanical devices to sophisticated digital instruments equipped with sensors, GPS, and real-time data transmission.
Cup Anemometers
The most common type, consisting of three or four cups mounted on arms that rotate as the wind blows. Widely used in wind farms due to their reliability and durability.
Vane Anemometers
These measure both wind speed and direction using a propeller and a tail vane. Ideal for portable applications and quick measurements.
Hot-wire Anemometers
Highly sensitive devices that measure wind speed based on temperature fluctuations caused by air movement. Used in research and precision applications.
Sonic Anemometers
Use ultrasonic waves to measure wind speed and direction. They provide accurate data even in extreme conditions, making them ideal for high-tech wind energy projects.
Laser Doppler Anemometers
Advanced technology that uses laser beams to detect wind movement. Best for research and highly precise wind measurements.
