Liquid level monitoring is essential for the industry. Conventional electronic sensor for this application is susceptible to electrical and heat conductivity that is risky for flammable substances. Hence, this paper introduces a single-layered rubber diaphragm fiber Bragg grating sensor to overcome this matter. In this experiment, the sensor used a straining mechanism as a sensing effect to monitor the liquid level ranging from 0-1200 ml. The result shows that the Bragg wavelength shifted towards the longer region when increasing the liquid level. The sensor exhibited an average sensitivity of 0.0042 nm/ml and average linearity of 96.376%, promising a good result for liquid level monitoring.
