The device is suitable for environments requiring continuous and accurate measurement of flow velocity and flow, and has the remarkable advantages of convenience in installation and maintenance, high reliability, high precision and the like.
Piezoelectric ceramics are functional ceramic materials capable of converting mechanical energy and electrical energy into each other. The principle of piezoelectric ceramics is to apply pressure to such a ceramic sheet, causing an opposite polarity of a charge to be generated across it, which then passes through a circuit to become a current, an effect called the piezoelectric effect.
The piezoelectric effect is reversible, for example, an alternating electric field is added to the piezoelectric ceramic plate, the ceramic plate becomes thinner and thicker, vibration is generated, and the common ultrasonic cleaning machine on the market is designed according to the principle.
