Developement of a Type of Ultrasonic Sensor forMeasuring Concentration of Liquid Solutions
Liu Zhenqing Wei Moan Zhu Shiming(Institute of Acoustics,Tongji Univ.)
In this paper,an ultrasonic sensor for measuring concentration of liquid solu-tions is described. It estimates the concentration of solution components via measuringthe velocity of the solution. A brief description of the principle and structure design isgiven. Influence of temperature, nonlinearity of ultrasonic wave velocity to the concentration,and the error of the sensor size are discussed.
