储罐液位检测方法综述

Survey on Detecting Method of Liquid Level of Tank

摘要: 储罐液位的准确测量对生产安全和管理起着重要的作用。储罐液位常用的检测方法主要有人工检尺法、差压式液位测量法、磁致伸缩液位测量法、超声波液位测量法、雷达液位测量法、光纤液位检测法。详细介绍了每种储罐液位检测方法的基本原理、优缺点以及它们各自的检测范围和精度，并对其进行了对比分析。

Abstract: The accurate measurement of liquid level of tanks is an important role in management and safety production. There are some common methods to detect liquid level of tank, such as hand gauging measurement, differential pressure liquid measurement, magnetostriction liquid level measurement, ultrasonic liquid level measurement, radar liquid level measurement, fiber-optical liquid level measurement. The basic principle, advantage and disadvantage, detection range and accuracy of every method of detecting liquid level of tank are presented in detail in the paper, and meanwhile a comparative analysis is given.
