Abstract

We demonstrate a new optical fiber liquid level sensor based on two sections of capillary optical fibers spliced between single-mode fibers. Last section without coating is in contact with the liquid. A measurement range of 60 mm is obtained when the structure is monitored in reflection by using a FBGs interrogator.
