摘要：
A method is disclosed to identify peak switching errors in an ultrasonic meter and how to correct for them. The method compares transit time measurements from two chords having different lengths to establish an error value. Depending on the magnitude and sign of the error value, any peak switching error can be identified and consequently corrected.
