Abstract
A method of ultrasound flow metering includes applying a first and second pulse train to an ultrasound transducer pair (T, T) positioned for coupling ultrasonic waves therebetween. Responsive to the first pulse train applied to T, Ttransmits an ultrasonic wave received as received ultrasonic wave (R) by Tafter propagating through fluid in a pipe. Responsive to the second pulse train applied to T, Ttransmits an ultrasonic wave received as received ultrasonic wave by (R) Tafter propagating through the fluid. During the pulse trains, Rand Rbuild up in amplitude to provide excitation portions. The pulse trains are terminated, so that Rand Rdecay as a damped free oscillation. Windowing is applied to Rand Rto generate windowed portions. A signal delay between tand t(ΔTOF) is calculated using only windowed portions, and a fluid flow is calculated from the ΔTOF.
