Types of Anemometers in UK


Anemometers are devices used to measure wind speed and direction. In the UK, various types of anemometers are used for different applications, ranging from meteorology to aviation, and even for hobbyist use. Here are the main types of anemometers commonly found in the UK:

  1. Cup Anemometers

Cup anemometers are among the most traditional and widely used types. They consist of three or four cups attached to horizontal arms, which are mounted on a vertical shaft. As the wind blows, it pushes the cups, causing the shaft to rotate. The speed of rotation is proportional to the wind speed. These are commonly used in weather stations and for general meteorological purposes.

  1. Vane Anemometers

Vane anemometers combine a wind vane with a propeller or a set of blades. The vane keeps the device oriented into the wind, while the propeller spins. The rotational speed of the propeller is used to calculate the wind speed. These are often used in environmental monitoring and HVAC applications.

  1. Hot-Wire Anemometers

Hot-wire anemometers use a thin wire electrically heated to a temperature above the ambient. As air flows over the wire, it cools the wire down, and the rate of cooling is used to determine the wind speed. These anemometers are very sensitive and are typically used in research and laboratory settings.

  1. Ultrasonic Anemometers

Ultrasonic anemometers measure wind speed and direction by sending ultrasonic sound pulses between pairs of transducers. The time it takes for the pulses to travel between the transducers is affected by the wind speed and direction. These devices are highly accurate and can measure wind in three dimensions, making them suitable for scientific research, weather stations, and aviation.

  1. Laser Doppler Anemometers

Laser Doppler Anemometers use the Doppler shift principle, where a laser beam is split into two and one part is directed into the airflow. The motion of particles in the air causes a change in the frequency of the reflected laser light, which is measured to determine the wind speed. These are highly precise and used in specialized research applications.

  1. Pitot Tubes

Pitot tubes measure wind speed based on the pressure difference between static and dynamic air pressure. They are often used in aviation to determine the airspeed of aircraft, but they can also be used in wind tunnel experiments and other aerodynamic studies.

  1. Pressure Plate Anemometers

Pressure plate anemometers consist of a flat plate that is pushed by the wind. The force exerted on the plate is measured and converted into wind speed. These are less common and generally used for specific applications like measuring wind load on structures.

  1. Handheld Anemometers

Handheld anemometers, which can be of various types including vane and cup designs, are portable and used for field measurements. These are popular among hobbyists, outdoor enthusiasts, and professionals who need to measure wind speed on the go.

  1. Agriculture and Horticulture

Farmers, horticulturists, and agricultural researchers utilize anemometers to assess wind conditions for crop pollination, pesticide spraying, and controlling microclimates in greenhouses and agricultural settings.

  1. Outdoor Enthusiasts

Outdoor enthusiasts, such as sailors, surfers, kite flyers, and paragliders, use handheld anemometers to gauge wind conditions for recreational activities and sports.

  1. Research and Education

Scientists, educators, and students across various disciplines use them for research purposes, conducting experiments, and educational demonstrations to understand principles of fluid dynamics, meteorology, and environmental science.

  1. Industrial Applications

They find applications in various industrial settings, such as assessing ventilation systems in factories, monitoring airflows in cleanrooms, and ensuring safe working conditions in hazardous environments.

  1. General Public

Individuals interested in monitoring weather conditions, wind speeds during outdoor activities, or maintaining personal weather stations may use them for hobbyist purposes.

In summary, they are utilized by a diverse range of professionals, enthusiasts, and industries in the UK for purposes ranging from weather forecasting and aviation safety to renewable energy production and environmental monitoring.
