Measuring Liquid Level Using Fiber Optic Sensing
Short Summary
Using DFOS to measure liquid level change when there is a temperature difference between liquid and air
Abstract
Fiber optic sensing can be used to measure changes in liquid level when there is a temperature difference between the liquid and surrounding air. One example is measuring the level of fuel in a tank, where fiber is especially advantageous as a sensor because it is chemically inert and does not pose an ignition hazard. This engineering note describes a test of fuel level measurements using the ODiSI strain sensing system.Â
