Patent ID: 7290455

Claim:
An ultrasonic meter comprising: a spool piece configured to couple within a flow of fluids; a first upstream transducer mechanically coupled to the spool piece; a first downstream transducer mechanically coupled to the spool piece, the first downstream transducer in operational relationship to the first upstream transducer; a transducer driver configured to drive the first upstream transducer and the first downstream transducer; a receiver circuit; a first multiplexer coupled to the first upstream transducer and the first downstream transducer; and a second multiplexer coupled between the first multiplexer, and the transducer driver and the receiver circuit; wherein the first multiplexer and the second multiplexer are configured to selectively couple the transducer driver to the first upstream transducer and the first downstream transducer; and wherein the first multiplexer and the second multiplexer are configured to selectively couple the receiver circuit to the second upstream transducer and the first downstream transducer.
