Abstract: A wellbore tool for measuring the density of a fluid flowing in a wellbore by a photon attenuation technique includes a tube defining a flow path for the fluid, a photon source at one end of the tube, and a photon detector arranged to receive photons which have passed along the tube. In a preffered implementation, a source which emits coincident photon pairs, preferably 22Na, is used. In this embodiment, the tube defining the fluid flow path has first and second relatively straight and aligned measurement portions disposed on opposite sides of the photon source, so that each measurement portion receives a respective photon of some of the coincident pairs for transmission longitudinally along it. Respective detectors at the other ends of the measurement portions receive respective ones of the photon pairs. The detected coincident photons are counted, and the density of the fluid is derived from the count rate.

Abstract: A differential pressure flow rate measurement apparatus comprises: a conduit having a flow passage for conveying a fluid flow, the conduit being adapted for connection to a downhole fluid flow line having a bore of predetermined transverse cross-sectional area; a flow energy dissipator which partially obstructs the flow passage and which is capable of imparting an angular velocity to the fluid flow and thereby causing a dissipative pressure drop in the fluid; and a pressure sensor for measuring said pressure drop. The flow passage, when viewed in the axial direction of the flow passage, projects an unobstructed transverse cross-sectional area which is at least 25% of the transverse cross-sectional area of said bore.

Abstract: A method and apparatus is disclosed for determining the flow rates of fluid phases in a pipe containing multiple fluid phases. A Venturi is provided to measure total volumetric flow rate measurement and a holdup measurement is taken approximately 3-10 pipe diameters downstream of the Venturi. The holdup measurement is made at a downstream location where a substantial amount of mixing occurs and the differences between the velocities of the fluid phases can effectively be ignored. The flow rates of the phases can thus be determined directly from the holdup measurements.

Abstract: A coating element has a liquid deflector member for diverting doctored coating liquid away from the surface of a coating applicator roll. The liquid deflector member is arranged beneath a blade member that removes excess coating liquid from the surface of the coating applicator roll. Excess coating liquid follows a path away from the coating applicator roll surface and down the active face of the liquid deflector member, thereby avoiding contamination of the applicator roll surface.
