The Computer Monitoring and Data Processing System in the Crude Oil Friction Reducing Experiment

The friction reducing loop experimental method dependant on maunal operation is mostly used now in China to cxamine the characteristics and regular prtterns of the various friction reducer either imported form abroad or procured at home. This method is not desirable, for it not only lakes tor much tine and effort, but it is quite fre quent with measuring errors and repetition, which has to be read personally.This article explains in detail the formation, soft-ware design and application of the set of the computer monitoring and data processing system latest developed for friction reducing experimental loop. It is proved by practice that this system is high in measuring precision, fast in data recording so that it saves energr, lighten labour intensiveness, and is of considerable automation, playing an important part in advancing the research on friction reducer.
