200-81000 Ultrasonic Anemometer
The 200-81000 Ultrasonic Anemometer is a three-dimensional no-moving-parts wind sensor. Two-dimensional anemometers meet the need for economy, but they ignore the important vertical wind component. The 200-81000 measure three dimensional wind velocity based on the transit time of ultrasonic acoustic signals. From speed of sound, sonic temperature is derived. Speed of sound and sonic temperature are corrected for crosswind effects.
