Abstract :
According to phase shift error hard to take out in measurement with single information source, based on multiple echo information sources, a liquid B/A measuring system is set up. Fusion of multiple information sources is adopted originally, and phase shift error generated by the transducer and measuring circuit is avoided by complementarity between different echo information. Accuracy and reliability of B/A measurement is improved obviously.
