差压节流装置的类型（1）孔板 孔板是最普遍、最悠久的一种经典流量节流装置，曾长期占据节流装置市场的魁首。但目前现场已无法满足它所要求现场直管段长度，制约了其应用。（2）多孔孔板 多孔孔板与经典孔板相比较最大的特点是：多孔孔板的节流件除了节流还有整流的作用，它解决了工业现场的直管段长度不长又要求必要的准确度的矛盾。在直管段长度较短（5~10D）的情况下，仍可达到士1%的准确度，值得关注。①发展历程 2002年，由美国Rosemount推出的调整孔板*4*5，(图1）首创了这类流量节流装置，据该公司称：前直管段长度大于5D情况下，可保持±1%准确度。2004年美国A+Flowtek公司推出了平衡式节流装置（图2B），2007年进入中国；2008年我国天津某公司推出了结构不同于美国A+Flowtek的整流式节流装置（图2A、C）。而测试数据表明，在前直管段仅2D时，准确度可达±1%，为5D时，准确度可达±0.3%，β值建议取0.5～0.65之间。在前直管段长度约30D的条件下，对图2所示的三种结构进行了流出系数的重复性、不确定度、线性度的测试比较，技术性能难分伯仲。
