ABSTRACT:
A device for measuring the proportion of a first liquid in a lower refractive index second liquid with which the first liquid is immiscible, such as oil in water. An unclad optical fiber, having an index of refraction between those of the two liquids but at least equal to and not more than ten percent greater than that of the first liquid. A light energy source and detector are connected by the immersed fiber and the light energy transmission measured to determine liquid proportions.
