Product Overview
The 3D ultrasonic anemometer is designed for real-time measurement of three-dimensional wind direction, wind speed, air temperature, and sound speed. It features fast response and high measurement accuracy, making it especially suitable for long-term observation.
Compared with mechanical anemometers, this product has no minimum starting wind speed and is not affected by mechanical wear or mechanical inertia. Compared with automatic weather stations and two-dimensional cup anemometers, it can accurately measure vertical airflow, which is important for studying near-surface wind vortex and turbulence phenomena. It also serves as an important complement to upper-air meteorological observation equipment such as wind profiling radar.
