Abstract: Based on Mach-Zehnder interference (MZI) principle, we propose a balloon-like optical fiber micro-liquid-level sensor and verify its performance through experiments. The sensor can ...

Abstract: Fiber optic-based liquid-level sensors (FOLLSs) can work in harsh environments with inherent advantageous features that only optical fiber offers, such as intrinsic safety, resistance to ...
