一、概述液体浓度的测量,本质上是它的密度或比重的测量。液体浓度的测量(密度或比重的测量)是一项重要的测量技术工作,它的在线自动测量也是仪表工程上的难题之一。到目前为止,在液体浓度测量方面我国还没有较为完整系统的资料,也没有系列化的在线测量仪表。糖厂制糖过程中,糖浆、石灰乳等物料的浓度都应连续检测。由于国内仅有的几种工业浓度计不是测量范围狭窄、使用条件高就是价格昂贵、维护困难皆不太适合糖厂使用。因此绝大多数糖厂的岗位工人只能用简 First, an overview of liquid concentration measurement, is essentially its density or density measurement. Liquid concentration measurement (density or specific gravity measurement) is an important measurement technology work, and its on-line automatic measurement is one of the problems in the instrumentation engineering. Up till now, there is no more systematic data in the measurement of liquid concentration in our country and there is no series of online measuring instruments. During sugar refinery process, the concentration of syrup, milk of lime and other materials should be continuously tested. As only a few domestic industrial concentration meter is not a narrow measurement range, high conditions of use is expensive, maintenance difficulties are not suitable for sugar mills. Therefore, the vast majority of workers in the sugar factory can only use Jane
