Ultrasonic Anemometers

Ultrasonic wind speed and direction sensors use ultrasonic sound waves to measure wind velocity. The lack of moving parts makes them appropriate for long term use in exposed automated weather stations and weather buoys where the accuracy and reliability of traditional cup and vane type anemometers can be adversely affected by sea salt in the air.
