摘　　要：在化工生产过程中,相当一部分材料都是以液体状态存在,有时需要测定其在容器内的液位高低,这就需要用到测量液位的压力传感器:液位计,来对液体的液位进行测量。对于专业化程度较高的化工生产过程中液体的液位测量需要用到高精度的专业性测量仪器,专业的液位测量仪表可以分为多种类型,都能够大大提高测量结果的准确性和可靠性,在不同情境下,应该选用不同的液位测量仪,以增加测量结果的准确程度,本文通过对化工装置中常用的几类液位测量仪表进行多方位的分析和思考,对化工装置中几种常用的液位测量仪表选型的实际应用进行简要探讨。In the chemical production process,a considerable part of the material is in the liquid state,and sometimes it is necessary to determine the level of the liquid in the container,which requires the use of a pressure sensor to measure the liquid level:a liquid level gauge to measure the liquid The liquid level is measured.For the liquid level measurement in the highly specialized chemical production process,high-precision professional measuring instruments are needed.Professional liquid level measuring instruments can be divided into many types,which can greatly improve the accuracy of the measurement results.Reliability.In different situations,different liquid level measuring instruments should be selected to increase the accuracy of the measurement results.This article conducts multi-directional analysis and thinking on several types of liquid level measuring instruments commonly used in chemical plants.The practical application of several commonly used liquid level measuring instruments selection is briefly discussed.
