Explanation:
Detailed explanation-1: -Two types of transducers have been used in ultrasonic machining; either piezoelectric or magnetostrictive: Piezoelectric transducer.
Detailed explanation-2: -The piezoelectric crystal is used for transmitting as well as receiving acoustic energy in an ultrasonic flow meter.
Detailed explanation-3: -Piezoelectric crystals have unique electromechanical properties. When an electric current is applied to a piezoelectric crystal, it starts to vibrate and these vibrations generate sound waves with frequencies between 1.5 and 8 MHz (i.e ultrasound).
