US 10,502,601 B2 · Detection of flow rate over dynamic range

Abstract

Aspects of the disclosure are directed to a obtaining a first plurality of signals associated with a fluid flow in a pipe, processing, by a processor, the first plurality of signals to obtain a first plot of power associated with first vortices in the fluid flow and a flow rate of the fluid flow in the pipe over a first flow rate range, determining, by the processor, that a maximum value of the power in the first plot corresponds to a maximum value of the flow rate included in the first flow rate range or that the power is increasing as a function of the flow rate towards an end of the first plot, and based on said determining, multiplying, by the processor, values of the first flow rate range to obtain a second flow rate range.
