Ultrasonic Velocimeter and its Application to Chemical Analysis

Wei Mo An Zhu Su Ming Sun Chang Jun  
In the first part of this paper,the principle and the error analysis of our ultrasonic velocimeter are presented,and a comparison with the“Sing Around Velocimeter”is given.In the second part the principle of components analysis,the factors causing errors,the experimental method for finding the relations among sound velocity,concentration and temperature,the methods for decreasing the influence of temperature are discussed.In the final part some successful applica- tions are reported.
