  • Methodology and apparatus for distinguishing single phase fluid flows from multiphase fluid flows using a flow meter
    Patent number: 10704939
    Abstract: An apparatus and method for sensing a fluid flow passing within a pipe, which fluid flow comprises at least a first fluid phase. The apparatus includes a flow meter having an array of sensors and at least one processing unit, which flow meter is adapted to sense the fluid flow passing within the pipe as it travels past the array of sensors and produce signals indicative of the presence of vortical structures convecting with the fluid flow. The at least one processing unit is adapted to: (a) produce a k-? plot using the signals indicative of the presence of vortical structures convecting with the fluid flow, and determine a k-? plot quality parameter that indicates the presence or absence of a second fluid phase within a fluid flow passing within a pipe; or (b) determine a shape factor parameter indicative of a presence or absence of a second fluid phase within a fluid flow passing within a pipe; or (c) both (a) and (b).
