Patent Number: 7,710,567

Title: Systems and methods for determining level and/or type of a fluid

Abstract: Methods and systems are provided for determining the density and/or temperature of a fluid based on the manner in which optical energy is affected as the optical energy propagates across a gap between opposing end faces of optical waveguides, or the manner in which the optical energy is reflected from interfaces of optical waveguides and the fluid.
