| Abstract: | 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. |
