Abstract
A multiphase flowmeter for detection of fluid flow by monitoring of vortex frequency or perturbation time of flight. The flowmeter includes a bluff body to facilitate formation of vortices during a consistent phase of a flowing fluid. Thus, monitoring frequency of the vortices may be employed to ascertain flowrate. Further, the bluff body may also facilitate formation of perturbations during transitioning phase of the fluid and include perturbation sensors at multiple known locations along the flow-path. Thus, analysis of perturbation detection times at the different locations may be used to ascertain flowrate even in the absence of vortices.
