Measuring Method of Intensity of Ultrasonic Cavitation Based on Time-difference Method

In allusion to problems of complex measuring process and expensive measuring equipment of current measuring method of intensity of ultrasonic cavitation, the paper proposed a measuring method based on time-difference method. It introduced measuring principle, designed a measuring device according to the measuring method, and verified the transmitting time-difference of ultrasonic in liquid with and without cavitations is proportional to input power in a certain range.
