摘　　要：系统采用光纤传感器采集液位高度变换信号,经光纤放大器将采集的光信号直接放大、光电转换后,实现单片机将数据处理显示并打印出液体位置值,这种系统特别适用于易燃易爆油田领域的液位检测。The system adopted optical sensor in order to acquisition parameter of liquid-level changes, the collected optical signals were amplified by optical amplifier directly, after photoelectric conversion, the specific liquid-level can be display or printing after data handing by single chip.This kind of system was used to check the liquid-level in inflammable and explosive oil field.
