新型液位检测技术的现状与发展趋势

Present Situation and Developing Trend of New Type of Measuring Technology for Liquid-level

文章介绍了工业生产过程中采用的光纤液位计、磁致伸缩液位计、音叉液位限位开关、差压式液位计、雷达液位计、伺服型浮子液位计等几种较新的液位检测仪表及其检测方法,并对几种液位计的特点进行了分析比较。文章最后指出,液位自动检测技术一方面需采用新的测量原理,开发新的液位检测仪表,扩大检测的手段,另一方面需朝着微机化和智能化方向发展。

The paper introduced some new kinds of measuring instruments for liquid-level used in industry production process and their measuring methods, such as fiber liquid-level meter, magnetostriction liquid-level meter, fork liquid-level limit switch, differential pressure type liquid-level meter, radar liquid-level meter and servo type float liquid-level meter, and analyzed and compared the characteristics of the several liquid-level meters. At last, it indicated that automatic measuring technology for liquid-level on the one hand must use new measuring principle, develop new measuring instruments for liquid-level and expand measuring way, on the other hand, it must develop facing on micro-computerization and intelligence.
