| Abstract: | Pressure and temperature are two important parameters in hydrostatic pressure based liquid level sensing. In this study, we propose a liquid level sensor based on hydrostatic pressure variation sensed by fiber Bragg grating (FBG1) attached to a bourdon tube. The water column pressure sensitivity coefficient of FBG1 is 0.072 nm/m. One more FBG2 is incorporated to avoid cross sensitivity of temperature. The temperature sensitivity coefficient of the FBG1 and FBG2 are 10.5 pm/°C and 10.2 pm/°C. The packaged sensor head can be placed inside a chamber and also easily mountable external to the tank for the measurement of liquid level. |
