浅析LNG接收站储罐测量仪表LIT工作原理

Brief analysis of LIT operating principle of storage tank measuring instrument in LNG receiving station

文章以福建LNG接收站储罐仪表测量系统为例,阐述了液位温度伺服计(LIT)液位测量原理、温度测量原理及高高液位报警动作原理,对今后储罐仪表测量系统液位温度伺服计(LIT)的运维工作、设备管理工作提供了理论基础,同时为其他在建及投产运营中的LNG接收站提供参考和借鉴。

Taking the measuring system of storage tank instrument in Fujian LNG Receiving station as an example,the paper expounds the measuring principle of liquid level temperature servo meter(LIT),the measuring principle of temperature and the operation principle of high liquid level alarm,which provides a theoretical basis for the operation and maintenance of the liquid level temperature servo meter(LIT)in storage tank instrument measuring system in the future.At the same time,it will provide reference for other LNG receiving stations under construction and in operation.
