Patent number: 7397976Abstract: An assembly senses fluid pressure variations within a passageway along a length of a flowline. A fiber optic cable is disposed axially within the passageway of the flowline. The fiber optic cable experiences a mechanical strain responsive to variations in the fluid pressure of the fluid communicating through the passageway of the flowline along the length of the flowline. The assembly also includes an enhancing layer surrounding the fiber optic cable. The enhancing layer is more responsive to the fluid pressure of the fluid communicating through the passageway of the cable than the fiber optic cable, which enhances the responsiveness of the fiber optic cable to the pressure by magnifying the mechanical strain associated with the fiber optic cable within a particular region of varying fluid pressure. Strain associated with the cable is communicated through back-reflected light.Type: GrantFiled: January 25, 2005Date of Patent: July 8, 2008Assignee: Vetco Gray Controls LimitedInventors: Alexis Mendez, Evangelos V. Diatzikis
