智能旋进漩涡流量计计量误差分析

Analysis on Metering Error of Intelligent Precession Vortex Flowmeter

华北油田第四采油厂的天然气计量主要以智能旋进漩涡流量计计量为主,但受工况变化等因素的影响,计量精度下降。从三个方面分析了引起计量误差的主要因素,提出了降低计量误差的改进措施。

Intelligent precession vortex flowmeters are mainly used to meter the natural gas in No. 4 Oil Production Company of Huabei Oilfield. Factors in variation of working condition impact metering precision of the flowmeter. Principal factors causing metering error are analyzed from 3 aspects and technical improving measures to decrease metering error are brought forward.
