ABSTRACT:
An ultrasonic flowmeter including a pair of alternately-excited upstream and downstream transducers, an acoustic pulse emitted by one transducer and propagated through the fluid being received by the other. The time delay difference between the upstream and downstream transit times is measured to determine the flow rate of the fluid. A single pulse power generating device is employed to excite both transducers, the device being coupled to the transducers through respective gates, each activated by an associated gate driver. Also included are logic means to periodically activate the device to produce power pulses and to alternately activate the gate drivers to cause the pulses to pass through alternate gates to excite one transducer and then the other.
