Liquid level sensor based on the change of fiber shape

LI Ye-fang,LIANG Xiu-ping,WANG Xiao-xu,XING Li(Department of Physics,Dalian University of Technology,Dalian 116024,China)  
The new type of liquid level sensor makes use of the self-change of fiber shape.In this paper,the experimental principle of fiber liquid level sensor and preparation of fiber tip are introduced.By using the experimental system of liquid level sensor,the reflection power is measured when the fiber tip is placed at different position in air,glycerin,alcohol and water.
