摘　　要： 本文提出一种基于压差法测量封闭体系中流体密度的方法,且所用设备简单,操作容易,可广泛用于食品、化工、制冷工业及能源技术。与微机相配合,可用来控制上述生产过程中流体的密度或浓度,以监视工艺过程或使过程正常运转。 A method for determining the density of fluids in closed systems based on the differential pressure has been given. The equipments used for this method are simple and easy to operate. It can be applied to food industry, chemi- cal industry, refrigeration and energy technology. When this system is connected with microcomputers, it can also be applied to the control of the density of fluids in the above mentioned process, in order to keep a close watch on process or make the process well run, or solve difficult problems which have been puzzling pro- duction and technology for a long time.
