Abstract:
A method, system and apparatus is disclosed for auto-tuning a circuit associated with an upstream transducer (UPT) and a circuit associated with a downstream transducer (DNT) for reciprocal operation in an ultrasonic flowmeter. The method includes exchanging signals between the upstream transducer and the downstream transducer; comparing at least one of respective maximum amplitudes of an upstream signal and a downstream signal and respective center frequencies of a Fast Fourier Transform (FFT) of the upstream signal and the downstream signal; and responsive to determining that at least one of the respective maximum amplitudes and the respective center frequencies do not match, correcting the mismatch.

Claim (Index 6):
The method as recited in  claim 1 , wherein, as a result of adjusting the impedance value of at least one of the first circuit or the second circuit so that the center frequency of an FFT of the upstream signal and the center frequency of an FFT of the downstream signal substantially match, an impedance value of the first circuit and an impedance value of the second circuit substantially match.
