目前,市场上的气体相对密度计主要是燃气相对密度计(指在相同温度和压力下,燃气密度对空气密度的比值)。燃气相对密度是燃气工业生产、科研和设计的重要技术特性指标。本文着重介绍气体相对密度计的测量原理和检测方法。一、测量原理气体相对密度计主要采用喷流法测定,喷流法原理是在相同温度和压力条件下,相等体积的不同气体经过给定结构的同一锐孔所需要的时间与各气体密度
Currently, the relative gas density meter on the market is mainly a gas relative density meter (the ratio of gas density to air density at the same temperature and pressure). Gas relative density is the gas industry production, research and design of the important technical characteristics of indicators. This article focuses on the gas relative density meter measuring principle and testing methods. First, the measurement principle Gas relative density meter mainly used jet method, the jet method principle is the same temperature and pressure conditions, the same volume of different gases through a given structure of the same sharp hole time and the gas density
