Peak switch detector for transit time ultrasonic meters
A method is disclosed to identify peak switching errors in an ultrasonic meter (120, 130) 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 (5) value, any p...

| Zusammenfassung: | A method is disclosed to identify peak switching errors in an ultrasonic meter (120, 130) 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 (5) value, any peak switching error can be identified and consequently corrected (500). |
