Abstract :
An optical fiber-based technique for liquid-level measurement is proposed. It is based on the power attenuation which occurs in an optical fiber, immersed in a liquid, when the liquid level varies. The theoretical analysis allowed a low-cost sensor prototype to be set up. The experimental results highlight the prototype capability of measuring liquid levels with acceptable sensitivity and repeatability
