摘要
本文介绍一种用单片机对大口径管道输送原油用的腰轮或刮板流量计进行多段自动补偿的方法，大大提高了流量计的精度和寿命，把流量计从０．２级提高到０．１级，对输油的交接计量提供了可靠的依据。
The paper introduces the use of a single chip micro-computer for auto-matic multi-stage compensation of a wheel type or plate type flow-meter for trans-fering of crude oil in a large bore pipe. This method greatly increases the accuracy as well as the life time of the flow meter, inproving the accuracy from 0.2 to 0.1 rank,providing reliable data for transfering measurement.
