摘要：

An ultrasonic device is described which can be used to measure the ultrasonic velocity, attenuation coefficient and characteristic impedance of liquid materials. A pulse echo technique is used for measuring the velocity and attenuation and a reflection technique for measuring the impedance. The device may be used to determine various physical properties of liquid materials, such as temperature, density and the particle size and concentration of dispersed phases.
