Limitations include reduced effectiveness in very strong winds and the need for occasional mechanical maintenance to keep them functioning properly.
Vane or Propeller Anemometers
Combining a propeller with a tail, these instruments measure both the speed and direction of the wind. The propeller reacts to the wind’s force, while the tail aligns the device with the current. They work best in open areas and provide continuous data, though placement matters because nearby obstacles can affect accuracy.
Hot-Wire Anemometers
These devices rely on a thin wire heated to a known temperature. As wind passes over it, the wire cools at a rate that indicates wind speed. Hot‑wire anemometers respond quickly to changes and provide highly precise readings, but they are delicate and require careful handling. Dust, moisture, and other environmental factors can interfere if the instruments are not maintained regularly.
Ultrasonic Anemometers
Ultrasonic models measure wind speed by sending sound waves between transducers. Changes in the time it takes for the sound to travel reveal the wind’s speed. Without moving parts, they offer durability, though extreme weather such as heavy rain or ice can impact readings. These units are often more expensive than simpler types.
Pressure Tube (Pitot Tube) Anemometers
Pitot tubes determine wind speed by measuring pressure differences between openings exposed to airflow. This differential pressure is converted into a reading that reflects wind velocity. They are commonly used in aviation and engineering for their accuracy in steady airflow. Routine cleaning and inspection are necessary to prevent debris from blocking the tube and compromising reliability.
