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 1):
A method for performing auto-tuning in an ultrasonic flowmeter including a first circuit associated with a first transducer of the ultrasonic flowmeter and a second circuit associated with a second transducer of the ultrasonic flowmeter for reciprocal operation, the method comprising:\n using a controller of the ultrasonic flowmeter to cause an upstream signal and a downstream signal to be exchanged between the between the first and second transducers, the upstream signal being transmitted from the first transducer to the second transducer and the downstream signal being transmitted from the second transducer to the first transducer; using the controller to compare at least one of a group comprising respective maximum amplitudes of the upstream signal and the downstream signal and respective center frequencies of a Fast Fourier Transform (FFT) of the upstream signal and the downstream signal; and responsive to the controller determining, based on the comparison, that at least one of the group comprising the respective maximum amplitudes and the respective center frequencies do not match, using the controller to adjust an impedance value in 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 after the adjustment.
