A study on characteristics of continuous wave ultrasonic anemometer

Abstract

This paper presents a study on the analysis of the characteristics according to the arrangement and number of receivers of a system that determines wind direction and velocity, by measuring the phase difference of continuous-wave ultrasonic waves. The sensitivity and measurement range were geometrically analyzed and experimentally verified according to the arrangement and number of receivers when the lengths of the movement paths of the ultrasonic signals and the angles of the movement paths with the wind were identical.
