FLUID SENSOR CABLE ASSEMBLY, SYSTEM, AND METHOD

摘要

A fluid sensor cable assembly and method uses one or more conductive bodies extending along an elongated core body for conducting a heating current to heat the cable assembly. The one or more conductive bodies also are configured to conduct an interrogation signal and to conduct reflections of the interrogation signal. One or more optical fibers extend along the length of the core body and include temperature sensitive elements at different locations along the length of the core body. The temperature sensitive elements measure heat flux out of the cable assembly at the different locations subsequent to heating the cable assembly and communicate the heat flux to a computer acquisition system.

1. A fluid sensor cable assembly comprising:
an internal core body having a length that is elongated from a first end to an opposite second end; one or more conductive bodies extending along the length of the core body, the one or more conductive bodies configured to conduct a heating current along the length of the core body to heat the fluid sensor cable assembly, the one or more conductive bodies also configured to conduct an interrogation signal along the length of the core body and to conduct reflections of the interrogation signal as distributed phase measurement signals to a computer acquisition system; and one or more optical fibers extending along the length of the core body at a designated radial distance from a center axis of the core body, the one or more optical fibers including a plurality of temperature sensitive elements disposed at different locations along the length of the core body, the temperature sensitive elements configured to measure heat flux out of the fluid sensor cable assembly at the different locations along the length of the core body subsequent to heating the fluid sensor cable assembly by the one or more conductive bodies and communicate the heat flux that is measured via the one or more optical cables to the computer acquisition system.
