利用差压变送器的表头,制作力平衡液面计的工作已经进行多年了。但近年来又有了新的进展:增加浮筒长度,用来测量液化气球罐的液位;扩大浮筒直径,用来测量两种比重差很小的介质界面;作为在线质量分析仪表,测量介质比重等,都获得了较好的效果。为此,进一步探讨这种仪表,提供正确的设计方法和设计数据,还是很有必要 The use of differential pressure transmitter header, the production of force balance liquid level meter has been for many years. But in recent years there has been new progress: increase the length of the float, used to measure the liquid level of the gas tank; expand the diameter of the float, used to measure two very small differences in the specific gravity interface; as an online quality analyzer, measuring the proportion of media Etc., have achieved good results. For this reason, it is still necessary to further explore such meters, provide the correct design method and design data
