摘　　要：本文提出了一种质量法液体流量标准装置量值偏差预警方法,介绍了预警方法的原理、流程及计算公式的推导。通过装置测得的流量、时间、密度和质量等参数,计算出量值偏差变异系数的差值,从而判断装置检测过程中是否需要预警。试验结果表明,该预警方法准确可靠。The paper presents a warning method of quantity deviation of mass method liquid flow standard device,introduces the principle, process and calculation formula of the warning method. Based on the parameters of flow, time, density and mass measured by the device, the difference of variation coefficient on measurement value deviation is calculated, so as to judge whether the warning is needed in the detection process of the device. The experimental results show that the method is accurate and reliable.
