The present application describes an optical fiber-based liquid level sensor, characterized by the use of grooves along
the length of the fiber, having engineering applications for liquid level measurements in locations of hard access under hostile conditions, with electromagnetic field interference, and without risk of short circuit in flammable environments. The liquid level sensor developed allows monitoring the rise or fall variation of the liquid level, with low signal loss, in environments with high environmental aggressiveness or flammable, where the use of electronic sensors is limited. In addition, this sensor can be used for various applications in the context of continuous and real-time monitoring through synchronization with other monitoring systems.
