探讨了速度式和容积式流量计用于天然气计量时,天然气压缩因子对其计量结果的影响;同时也探讨了无压缩因子修正或修正不当而造成的二次仪表计量误差.
The effect of natural gas compression factor on the measurement results of natural gas when the velocity and volumetric flowmeters were used in natural gas metering was also discussed. Meanwhile, the error of secondary instrument measurement due to improper correction or correction without compression factor was also discussed.
