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 7):
Circuitry for auto-tuning an ultrasonic flowmeter that includes first and second transducers, a first circuit associated with the first transducer and a second circuit associated with the second transducer, the integrated circuit comprising:\n a microcontroller operably connected to the first and second transducers; memory operably connected to the microcontroller and containing instructions that, when executed by the microcontroller, cause the microcontroller to:\n control an exchange of an upstream signal and a downstream signal between the first and second transducers in which the upstream signal is transmitted by the first transducer and received by the second transducer and the downstream signal is transmitted by the second transducer and received by the first transducer; \n 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 \n responsive to 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, 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.
