在炼油、化工、化纤和食品工业生产过程中,很多地方需要对液体的重度进行连续地自动测量和控制。采用重度测定槽为检测装置,以差压变送器为一次仪表的自动测量重度的方法是一种简单易行的方法。该测量装置结构简单,制作方便,测量精度较高,並且有温度自动补偿的性能。现结合我厂仿制 In the refining, chemical, chemical fiber and food industry processes, there is a need in many places to measure and control the severity of liquids continuously and automatically. It is a simple and easy way to measure the severity automatically by using the differential pressure transmitter as a measuring instrument. The measuring device has the advantages of simple structure, convenient manufacture, high measuring accuracy and automatic temperature compensation. Now combined with my factory imitation
