标准体积管检定过程中的误差来源

Error Origin in Course of Prover's Calibration

着重介绍了容积法（称重法）检定标准体积管和用标准体积管检定计量体积量（质量）流量计的检定原理及其检定修正公式的理论分析，以及在实际检定过程中各种误差的来源分析，消除或减小各种误差的有效方法。

This article emphatically introduces the calibration principle of calibrating prover by using of volume method and calibrating metering volume flowmeter by using of prover and the theory analysis of their calibration revision formulae, various error source analysis in course of practical calibration and the valid method to eliminate or decrease various errors.
