Abstract：Scraper flowmeter is a kind of dynamic measuring instrument widely used in the process of crude oil measurement and transfer. Its measurement performance, measurement accuracy, and instrument stability will directly affect the economic interests of both parties in crude oil trading. This paper sorts out the previous verifications of scraper flowmeters at a certain oil transportation terminal, draws a historical curve of verification errors based on the data, and analyzes the causes of errors that affect scraper flowmeters in terms of verification, daily operation, and routine maintenance, and conducts in-depth research on them. , Propose corresponding reasonable countermeasures to improve the measurement accuracy of the scraper flowmeter for the reasons of the error.
