摘　　要：针对可调K系数的电磁流量计的周期性校准工作,依据国家计量检定规程JJG 1033-2007《电磁流量计》的要求,研究了电磁流量计线性特征,引入系数修正因子θ,介绍了在不对流量计的线性度调整而仅对其斜率K进行调整的前提下,将流量计的最大误差调整到当前线性最优情况的一种快速有效的方法。For calibration of electromagnetic flowmeter with adjustable coefficient K,according to the national verification regulations JJG1033-2007Electromagnetic Flowmeters,linear characteristic of electromagnetic flowmeter was studied and the coefficient of correction factorθwas introduced.This article introduces a efficient method of adjusting the flowmeter to best condition by only changing the flowmeter K coefficient value.
