Applications:

Piezoceramic transducers to produce ultrasonic signal for the measurement of flow rate of liquid in a pipeline where direct contact of the liquid is a concern.

An ultrasonic flow meter can be used to measure the flow rate of a liquid passing a predetermined point in a pipe. As a measuring method that will not disrupt the liquid flow, piezoelectric transducer is placed on the tube wall and transmits ultrasonic wave into the liquid perpendicularly to the direction of the flow. The frequency shift between the transmitted and received ultrasonic waves is evaluated and velocity of liquid in a pipe is determined.

PZT Material:

- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.

- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.

- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
