摘要
本文介绍以光纤作为传感介质的智能流量计。在系统设计中，采用光纤微弯曲效应传感涡流，从而实现仪表防爆和远距离传输；二次仪表用ＭＣＳ—５１单片机实现数据处理、显示、打印、变送和上下位机通信。
This paper introduces an intelligent vortex flowmeter characteristics. First, the minorbending effect of fibre-optics is used to detect vortex. As a result, the instrument has high anti-enplosion capability and long-distance data transfer ls possible. Second, as low speed, phase-locked fre- quency-multipler is employed to increase the precision of the meter.
