摘要： A distributed temperature sensor, a method of determining temperature, and a processing system to compute temperature are described. The sensor includes an optical fiber disposed in an area where temperature is to be measured, a primary light source to inject light into the optical fiber, and a secondary light source to inject light into the optical fiber. The sensor additionally includes a photodetector to detect backscatter light energy from the optical fiber the backscatter light energy including Stokes Raman scatter or anti-Stokes Raman scatter and primary Rayleigh scatter resulting from the primary light source and secondary Rayleigh scatter resulting from the secondary light source, and a processor to determine temperature based on a ratio of the Stokes Raman scatter or the anti-Stokes Raman scatter and a combination of the primary Rayleigh scatter and the secondary Rayleigh scatter.

摘要： A flowline branch structure (10) has at least one inner branch assembly with an inner flowline branch and at least one inner flowline pipe attached to and communicating with the inner flowline branch. At least one outer branch assembly (12) of the flowline branch structure has an outer branch housing disposed around the inner flowline branch and at least one outer pipe (14) disposed around the inner flowline pipe and attached to the outer branch housing. A generally annular space is defined between the inner and outer branch assemblies. At least one wiring element including an electrical heating element is disposed in the sealed space on an outer side of the inner branch assembly. The, or each, wiring element extends in one continuous length across an interface between the inner flowline pipe and the inner flowline branch. This reduces the number of connections necessary to create the flowline branch structure.
