Design and Experiment of Ultrasonic Anemometer Using TDC-GP2 Time-to-Digital Converter

Abstract:

An ultrasonic anemometer using TDC-GP2 high-accuracy time measuring chip is studied in this paper, the design of software and hardware parts and principle of flying time measurement using TDC-GP2 chip are also discussed in detail. Under this scheme, a prototype has been fabricated, with simpler circuit architecture. A wind tunnel experiment of the prototype was conducted, the test result shows that the ultrasonic anemometer can measure wind speed up to 39.9m/s, and the measurement error does not exceed 0.3m/s when wind speed is below 10m/s, or 3 percentage when its above 10m/s. Wind directions vary from 0 to 359 degree can be detected with accuracy of 3 degree.
