流量计体积管检定系统改造分析

Reconstruction and Analysis of the Measurement System for Volume Tube of Flowmeter

本文分析了体积管检定流量计的原理和检定过程中的干扰因素及其产生的计量误差, 针对存在的问题, 将体积管标准装置升级改造为静态质量法液体流量标准装置, 并分析该套改造装置的优势.

This paper analyzed the principle of the volume tube verification flowmeter, the interference factors and the measurement errors in the verification process. In view of the existing problems, the standard device of the vol- ume tube was upgraded to a static mass flow standard device, and the advantages of the set were analyzed.
