The present invention proposes a system for measuring the water-oil interface level based on the fluid thermal properties. To overcome limitations related to the interface level in oil separation processes, an interface level sensor must detect water, oil, emulsion and foam layers. Furthermore, maintenance costs must be low and the time between maintenance must be high, in order to obtain high production rates and more reliable control of the oil separators. Optical system for measuring the water-oil interface level from fluid thermal properties comprises single-mode optical fiber (), FBG (), PTFE tube (), connection (), flange (), optical connectors () and optical interrogator ().
