An ultrasonic Velocity Profile (UVP) has been continuously improved for flowrate measurements. Since the UVP can visualize a flow profile along a cross section of pipelines, it provides a significant advantage over other conventional methods such as differential pressure, turbine, and vortex. Previously, the UVP was realized by means of autocorrelation, fast Fourier transform, and wavelet as the signal-processing method. An Estimation of Signal Parameters via Rotational Invariance Technique (ESPRIT) has been widely used in a field of communication engineering for a high-resolution signal processing. This is the first of utilizing the ESPRIT technique in fluid mechanics for a flowrate computation. To guarantee the proposed idea, the results were compared with a standard electromagnetic flowmeter. Lab experiments were required to demonstrate the accuracy of flowrate measurements.
