气体流量积算仪内部参数对计量准确性的影响

Influence of Internal Parameters in the Gas Flow Calibration Meter on the Accuracy of Measurement

气体流量积算仪是现在燃气贸易计量中常用的一种电子仪表,在应用中大部分积算仪内部的参数是厂家出厂时就设定完毕的,但现场情况常常是错综复杂,因此由于参数的不合理造成计量不准确的情况时有出现,那么根据现场情况重新设置或较对参数对于日后的准确计量就有着重大的意义,本文详细分析了其内部参数对计量准确的影响。并以几种国内外常用积算仪为例进行了讲述,方便了日后对流量积算仪的技术管理,也为积算仪在现场能够良好的应用打下基础。

Gas Flow calibration meter is an electronic measuring instrument commonly used in gas trade now.Internal parameters of the calibration meter was mostly completed set by factory,but the fieldwork conditions are often intricate,so the inaccurate measurement caused by the irrational parameters setting occurred.Then reset the parameters according to the situation,or more accurately correct the parameters has a great significance for the future.The paper gives a detailed analysis the internal parameters influence on the accuracy of measurement,and takes several Gas Flow calibration meters as examples,it has facilitated the technical management of flow calibration meter in future,also it set a good application at fieldwork to the meter.
