SATI Series - Sonic Anemometer/Thermometer - Technical Data

The Sonic Anemometer/Thermometer is a microcomputer-based wind sensor capable of measuring wind velocities in one, two, or three axes with reliable accuracy. The instrument is designed to measure wind velocity components by transmitting and receiving sonic signals along the fixed orthogonal directions. The microcomputer electronics then processes this information and calculates the wind velocity in each axis. The sonic offers several major advantages over cup anemometers and bivane systems. Since there are no moving parts to come into dynamic equilibrium with the airflow, the sonic responds rapidly to wind velocity fluctuations. It responds linearly to wind velocity and is free from contamination from other velocity components as well as pressure, temperature, and relative humidity. The calibration of the sensor is established by its design parameters and, therefore, can be used as an absolute instrument.
