摘　　要：双向流均速管传感器不但具有单向流均速管传感器的所有功能,还能运用于介质的双向流动测量和防堵塞功能。在双向流均速管传感器的两型腔内,分别置入引压管取压,可更准确引入管道的平均全压,可提高差压输出和测量的准确性。经实流检定和现场应用,流量系数稳定、重复性好、测量精度高。The bidirectional flow averaging velocity tube sensor not only has all functions of unidrirectional flow averaging velocity tube sensor,but also can be used to measure the bidirectional flow of fluid and Prevent blockage.the pressure pipe is-placed into the double cavity of bidirectional flow averaging velocity tube sensor respectively.In this way,the average pressure of the pipeline can be introduced more accurately,and the accuracy of differential pressure output and measurement can be improved.Through the real flow verification and field application,the flow coefficient is stable,with good repeatability and high measurement accuracy.
