“…Liquid level monitoring is necessary in the industry and in the scientific research field [1]. The designs of liquid level sensors indicate the preset height of liquid levels, including magnetic [2], vibrant, capacitive [3], microwave [4], ultrasonic [5], and photoelectric liquid level sensor [6,7]. The traditional glass tube liquid level gauge is widely utilized in simple structures for clear indication and visual observation [8,9].…”

The working principle of the refractive-type fiber optic liquid level sensor is analyzed in detail based on the light refraction principle. The optic path models are developed in consideration of common simplification and the residual liquid film on the glass tube wall. The calculating formulae for the model are derived, constraint conditions are obtained, influencing factors are discussed, and the scopes and skills of application are analyzed through instance simulations. The research results are useful in directing the correct usage of the fiber optic liquid level sensor, especially in special cases, such as those involving viscous liquid in the glass tube monitoring.
