A system, method, and apparatus for reducing ringing effects associated with a transducer comprises a transducer body, a transducer cap, a piezoelectric element formed in the cap, and a damping material formed around the piezoelectric element wherein the damping material suppresses a ringing effect associated with the transducer, while an O-ring is used together with damping material to support high pressure applications up to 230 bars.

Ultrasonic transducer

An ultrasonic meter includes a group of piezoelectronic ceramic arrays, wherein each array comprises array stripes, such that a signal associated with each array can be split and a required phase shaft added to the signal to obtain simultaneously different data from the signal such as, for example, the transit time of a direct path and crosstalk. The smaller array can provide a higher aperture and improve the use of crosstalk.
