1、经典节流装置不再辉煌 早于1890年，在美国俄亥俄州已开始试用孔板测流量。1912、1913、1916年T.R.韦默思；E.O.希克斯坦；E.G.贝利等人相继发表了有关孔板的制造、应用的相关数据，开启了长达百年顽强、艰苦的研究历程，使其成为流量测量中软实力最强的仪表*1*2，由于以下优点，曾取得占节流装置市场70%以上的骄人业绩；但也存在一些难以逾越的缺点。（1）优点①强大的软实力 积累了超过百年丰富的科研数据，使用经验，在此基础上制定了标准，并不断修改完善。使制造、应用有据可查，有法可依。 ②无需标定 有成熟的标准，制造厂只需按标准生产，可无需标定，就可知流量系数等相关数据，节约了生产成本和周期。 ③可承受恶劣工况 经典流量节流装置，一、二次表分离，较许多新型节流装置可耐恶劣工况，如：高温、高压、粉尘、振动、噪声、电辐射等。
