提出了一种基于双锥光纤马赫-曾德尔干涉仪（DTFMZI）的低成本、结构简单的在线式液位传感器。在这封信中，结构，工作原理，实验结果，并讨论拟议的光纤液位传感器进行了研究。实验结果表明，DTFMZI传感器具有很高的灵敏度和线性响应，在10 cm的测量范围内达到了2.8 nm/cm的灵敏度。
A low cost, simple, and in-line liquid level sensor based on a dual-tapered fiber Mach-Zehnder interferometer (DTFMZI) is proposed. In this letter, the configuration, operation principle, experimental results, and discussion for the proposed fiber-optic liquid level sensor are investigated. Experimental results show that the proposed DTFMZI sensor is highly sensitive and linear in the response; a good sensitivity of similar to 2.8 nm/cm within the whole measurement range of 10 cm is achieved in this letter.
