一、前言在液位测量和界面控制中,干簧式液位计有很多优点。因而在1978～1982年之间,它先后在苏、英、日、美、联邦德国等国获取了专利。我国在这一时期内也有生产。但这类仪表还存在测量显示不连续,均未标准化、系列化的技术难题需待解决。北京自动化仪表四厂采用以阶跃极小的折线代替平滑曲线的办法,大量增加干簧管数目,使阶跃减小,并用数字电压表进行测量。因此获得了我国1985年国家级科技进步三等奖,但标准化仍未解决。为了完善这类仪表,我们研制成了磁浮子液位计。它吸取了干簧式液位计的优点,去除了缺陷,是能连续测量显示的标准化系列液位测量仪表。因其总误
First, the introduction In the liquid level measurement and interface control, reed level meter has many advantages. Therefore, between 1978 and 1982, it successively obtained patents in countries such as the Soviet Union, Britain, Japan, the United States, the Federal Republic of Germany and so on. Our country also has production during this period. However, there are still such measurement instrument shows discontinuities, are not standardized, serialization of the technical problems to be solved. Beijing Automation Instrumentation Factory adopted a step-by-step polygonal curve instead of a smooth curve, a substantial increase in the number of dry reed, so step down, and measured with a digital voltmeter. Therefore, we won the third prize of China’s state-level scientific and technological progress in 1985, but the standardization has not yet been resolved. In order to improve such instruments, we developed a magnetic float level gauge. It draws on the advantages of reed-type level gauge, eliminating the defects, is a continuous measurement of the standard display of liquid level measuring instruments. Because of their total error
