摘要
以环形孔板为流量检测件的新型仪表——环形孔板流量计,已经在冶金、石化、采油、化工、电力等行业得到了成功应用。将环形孔板流量计与标准孔板流量计、V形锥流量计进行性能比较,介绍了环形孔板流量计在典型环境中的应用,说明了环形孔板的原理和特点,最后从理论和实践两个方面证明了环形孔板流量计良好的测量性能。
The new type of annular orifice plate has been successfully applied in metallurgy,petrochemical,oil,chemical,electric power and other industries.The characteristics of annular orifice flowmeter are compared with the one of standard orifice and V-cone flowmeter,and the application of annular orifice plate in typical environment is introduced thus the principle and features of annular orifice are illustrated,and the good measurement performance of annular orifice are verified theoretically and practically.
