（3）科学试验与建立标准   为什么经典流量节流装置能经历百余年辉煌的历史，靠的是反复认真进行科学试验，再将试验结果用于现场进行验证，如此不断地测试、提升。将这些成果总结成为标准，才有稳固的基础。令制造有法可依，使用有据可查。（4）阻力件试验势在必行   新型流量节流装置的一个突出特点在于无需较长的直管段长度，即可维持较高的准确度，这个特点必须厂家用科学的试验数据予以验证，且由第三方予以证明，而不能只是引经据典，用别人的实验数据来证明自己产品的技术性能；也别拿国外的数据来唬人，经验证明国外的有些数据也未必名副其实，不少有夸大之嫌，或有意给出虚假数值，以保护商业利益。要创立民族的品牌，没有捷径可走，必须脚踏实做实验，一丝不苟测数据。要研发新型流量节流装置，阻力件试验势在必行，建立相应的试验室迫在眉睫。
