Based on the lithium bromide solution concentration measurement system

本文针对"膜反转板式降膜热质传递过程研究"中测量溴化锂水溶液浓度的需求,基于比重计法测量浓度的原理,利用电磁力反馈原理、数据采集等研究设计了溴化锂溶液浓度自动测量系统,并进行了相应实验平台的搭建和调试。利用实验搭建的装置进行溴化锂溶液样本的浓度测量表明,本装置可快速准确地实现溴化锂溶液的浓度测量,操作方便。新的测量方法,为其他浓度测量系统的开发提供了一些思路,是现代电子测量自动化、智能化、网络化和标准化的趋势的一个崭新的尝试。

To meet the requirement of measuring the LiBr solution concentration in ＇The Research on the heat and mass transfer process of plate falling film absorber with a film-inverting configuration＇,by analyzing the principle of the concentration measurement method by using the Hydrometer,and based on the principle of the electromagnetic force torque feedback balance,Data acquisition and etc.,this paper designed a new kind of LiBr solution concentration automatic measurement system,built the corresponding experiment system and tested it. The test results of the experiment system showed that,this new system can measure the LiBr solution concentration accurately,conveniently and quickly. The new measuring method provides some ideas for other concentration measuring system,it is a new try for modern electronic measurement automation,intelligence,networking and standardization trend.
