液氨贮罐液位测量的误差分析及解决方案

The error analysis and settlement project of Lam tank level measurement

本文通过一个具体的实例 ,详细分析了差压式液位测量系统的误差来源及其消除方法 ,提出了在DCS中充分利用现有仪表资源构建新型测量系统 (软仪表 )的基本思想。

This article analyses the main cause making error and the corresponding method remedying it in level measurement by press difference, put forward the idea about composing a new measurement with the current instrument in DCS, via an example.
