Abstract

A simple optical fiber sensor devoted to measurement in situ of the density of water in oil is described. It is composed of two bundles of fibers. One bundle of fibers transmits light to the droplets of water spread in oil while the other acts at the same time to collect a part of the back-scattered light and to carry it back to a photodetector. The probe configuration is of line- by-line arrangement. With such a device, for the oil containing a very high density of water, the response is an increasing function of the density. The sensor can measure the density of water in oil in the range from 0 to 20%.
