FLOW MONITORING TOOL

摘要

A system for measuring conditions in a wellbore (10) includes tubing (12) extending into the wellbore. A first fiber optic cable (20) extends axially along a fist surface portion of the tubing and has at least one signal generation gauge (24) located at a predetermined location for producing a generated acoustic signal (26) that propagates outward from the generation gauge and through the tubing. A second fiber optic cable (22) extends axially along a second surface portion of the tubing and is operable to receive a resulting signal of the generated acoustic signal so that wellbore parameters proximate to the predetermined location can be determined. The second fiber optic cable (22) is spaced apart from the first fiber optic cable (20) and is operable to transmit data of the resulting signal to a receiver (30).
