摘要
近年来，基于光弹效应的光纤液位传感器发展迅速。其传感器内采用光桥补偿光路，可以克服多种外界因素对测量产生的不利影响．但由于它的绝对压强测量原理，致使它在浮顶油罐上的应用一直是人们所关注的问题．本文从理论和实验两方面证明，在浮顶罐的液位测量中，运用ＩＭ８５－Ｉ型光纤液位仪，可以获得与开顶罐相同的测量精度．而与浮顶的重量及浮顶与罐壁的摩擦力无关．
In this paper, it has been proved theoretically and experimentally that by use of IM85-1 Fiber-optic Liquid Level Sensing Device forthe floating-top tanks, the measurement accuracy is the same as that ofopen-top tanks, and is irrelevant to the weight of the floating-top and thefriction betweep the floating-top and the well of the tanks
