differential pressure device的用法详解
Differential pressure device是一种流量计,它可以测量管道内流体或气体的流动速度,以及管道内部温度、压力等参数。这种设备一般使用两个管道来完成任务,其中一根气体流出口的管道,另一根管道称为返回管道,这根管道可以使流体从流出口回到进口。两个管道之间的压力差是流速的指示,当流速改变时,压力差也会发生改变,从而用以测量流速。
传统的differential pressure device由一个压力叠加模块和一个压降表组成,压力叠加模块的作用是将进口压力和返回管道的压力叠加到一起,而压降表的作用是从中读取压力差,从而测量流量。
近年来,differential pressure device在技术上有了很大的进步,新的设备使用传感器和模拟/数字电子电路,可以实时检测流速,而且可以将流速的数据发送到计算机进行分析。
总之,differential pressure device就是可以测量流体或气体流速的一种流量计,它可以应用于各种场合,例如气体流量检测、工业过程控制、流量计量等。
