| 摘 要： | 主要从弯管流量计的下限提出了自己的几点看法.弯管流量计虽然距今已有近百年的历史,但是只是近十多年来在我国才有了较大发展和广泛应用,由于流体受到传感器的束缚,迫使流体按照弯管的曲率在管道中作类似的圆周运动,流体产生的离心力使传感器的内外侧壁产生压力差通过差压变送器检测出来,转换为标准信号输出给上位机或二次仪表.

| Abstract: | In this paper,some personal views on proposed flow from the Minimum fluid velocity of elbow flowmeter.Although elbow of flowmeters have a history of nearly 100 years,they are developed greatly and widely used in recent 10 years.The fluid is constrainted by sensors,therefore,the fluid is forced to move circumferentially similarly in the pipe according to the curvature of the elbow.The centrifugal force produced by the fluid generated pressure difference on the inner and outer wall of the sensor,and the difference is detected by differential pressure transmitter and transformed into standard signal which is output to upper computer or secondary meter. |
