Light Path Model of Fiber Optic Liquid Level Sensor Considering Residual Liquid Film on the Wall
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...
