AI Technical Summary

Technical Problem

Existing ultrasonic flow measurement equipment suffers from insufficient measurement accuracy in media measurement, especially when considering the flow profile of the flowing medium and the fluctuation of the measuring tube size, it is difficult to achieve high-precision measurement.

Method used

An ultrasonic transducer array consisting of multiple individually controllable transducer elements is arranged on the inner and outer peripheries of the measuring tube. By flexibly controlling the excitation and reception of different pressure distributions and wave modes, it ensures the excitation and detection of the plane wavefront in the measuring tube and compensates for the size fluctuations of the measuring tube.

Benefits of technology

It achieves high-precision measurement of medium flow, can take into account all velocity components of the flow profile, reduces interference from the reflected signal from the measuring pipe wall, and improves the accuracy and flexibility of the measurement.
