AB  - Purpose This paper aims to propose a liquid level sensor with a multi-S-bend plastic optical fiber.Design/methodology/approach The principle of liquid sensing used is based on the leakage of higher modes out of the fiber and repeated regeneration in the following bend sections. Therefore, a propagation loss was introduced in every bend section of the fiber with the loss depending on the refractive index of the environment.Findings Therefore, a continue shift in the liquid level can be detected by observing changes in the propagation loss of the fiber. The sensor features compactness and a flexible resolution.Originality/value Compared with the exited ones, the sensor has capability of continue liquid measurement and a greater measurement range.
