Improved liquid level sensor by using a multi-capillary structure. In International Conference on Optical Fiber Sensors, 28th International Conference on Optical Fiber Sensors (pp. 1-4).

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.application/pdfeng© 2023 Optica Publishing Group.
