Ultrasonic Anemometers
An ultrasonic anemometer (or sonic anemometer) measures linear components of the wind vector by determining the effect of the wind on transit times of acoustic pulses transmitted in opposite directions across known paths. It operates on the principle that the propagation velocity of a sound wave in a moving medium is equal to the velocity of sound with respect to the medium plus the velocity of the medium. The wind velocity vector is determined by measuring the wind speed along three independent linear paths, for example, three orthogonal paths. The sonic anemometer is an absolute instrument and has the advantages of a very short time constant and an absence of moving mechanical parts. (Source: AMS Glossary)

The 200-7000 WindSonic Ultrasonic Anemometer is a lightweight unit of a robust, high strength construction. Without the need for expensive on-site calibration or maintenance, and with a corrosion free exterior, WindSonic is a true fit and forget unit. |
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 measures three dimensional wind velocity based on the transit time of ultrasonic acoustic signals. |
The 200-85000 Ultrasonic Anemometer is a 2-axis, no-moving-parts wind sensor. It is ideal for general meteorological applications requiring accurate, reliable wind measurement. |
