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.

Abstract: Apparatus and methods for decreasing pressure of drilling fluid within a region between an impeller and a housing of a power generation module (PGM). The apparatus comprises a shaft extending from and rotatable relative to the housing; The impeller is coupled with the shaft external to the housing and includes a group of blades that rotate the impeller as the drilling fluid flows past the PGM. The impeller further includes another group of blades that decrease the pressure of the drilling fluid within the region between the impeller and the housing when the impeller is rotating.
