In the ultrasonic ranging system, the performance of the ranging algorithm directly affects the performance of the ranging system;The operation speed of the method directly affects the performance of the ranging system. From the perspective of information theory, the ultrasonic ranging process is ac

A physical picture of a piezoelectric disc-type transducer designed and fabricated. In order to reduce the influence of multipath noise, using the aforementioned sound field Fresnel zone, the ultrasonic transducer is slightly higher than the radiating surface (or acoustic window) of the piezoelectri

Applications of ultrasonic liquid concentration detection The principle of ultrasonic liquid mud concentration detection is based on the ultrasonic wave in the liquid velocity and the liquid concentration and temperature .
