SATI Probe Styles - Ultrasonic Anemometers - Brochure

The Applied Technologies, Inc. (ATI) Sonic Anemometer/Thermometer is a microprocessor based wind sensor capable of measuring wind velocity 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 fixed orthogonal directions, with the exception of the A style probe, which is non-orthogonal. The microcomputer electronics then process this information and calculates the wind speed for each axis. Since there are no moving parts to come into dynamic equilibrium with the air-flow, the Sonic Anemometer/Thermometer 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 wind instrument. That is correct, an Absolute Wind Instrument, with an accuracy that is controlled by the operator.
