Discriminating device fluids with different indices measuring device and the volume fraction of at least one fluid into a stream of immiscible fluids including application.

摘要

Dispositovo discrimination fluids with different indices, comprising a fiber optic coupler (4) with three ends to which are respectively connected a light source (1) with semiconductor in which the intensity is modulated, a photodetector (2 ) semiconductor and a multimode optical probe constituted by an optical fiber (3) with the same index profile that the coupler fibers, wherein the end (3a) of the optical fiber is shaped tip obtained by hot drawing.
