Anemometers

An anemometer is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns. Anemometers measure wind speed by the amount of wind pressure against a surface, such as a cup or a propeller, or by using sonic pulses.

SISCO offers digital vane anemometer, 3-cup anemometer, ultrasonic anemometer, thermal anemometer, handheld anemometer for weather station 5 anemometer types for measuring wind speed. Anemometers are used at almost all weather stations, from the frigid Arctic to warm equatorial regions. Wind speed helps indicate a change in weather patterns, such as an approaching storm, which is important for pilots, engineers, and climatologists.

What does an anemometer measure?

1. Instantaneous wind speed: Cup anemometers, for example, use rotational speed to reflect real-time wind speed.
2. Average wind speed: Wind direction and speed recorders, for example, can calculate a 2-minute or 10-minute average.
3. Fluctuating wind speed and turbulence: Hot wire/hot film anemometers can measure complex parameters such as airflow pulsation spectrum and Reynolds stress.
4. Vertical wind speed: Acoustic anemometers use multiple pairs of ultrasonic probes to achieve three-dimensional wind speed measurement.

What does an anemometer used for?

1. Meteorology and environmental monitoring: Used for weather forecasting, wind energy assessment, pollution dispersion research, and more.
2. Fire protection: Measuring wind speed at the air outlet of smoke and exhaust systems to ensure compliance with safety standards.
3. Power and petrochemical: Monitoring wind speed during high-altitude operations or hazardous environments to ensure operational safety.
4. Agriculture: Controlling greenhouse ventilation and fertilization.
5. Wind power: Optimizing wind turbine angles for efficient wind energy utilization.
6. Research and education: Studying turbulent flow characteristics or creating simple anemometer models for teaching experiments.
