摘要
科氏力质量流量计的基本原理是当流体流经一段进行着角振动(同相位振动)的管子时,在管子上就会产生科里奥利力,其大小正比于流体的质量流量。在角振动着的管子上又叠加了一个扭转振动(反相位振动),扭转角的大小也就正比于流体的质量流量。该流量计于20世纪80年代问世,目前国际上只有美国、德国、英国、日本、丹麦等少数国家能进行生产。能够对浆状、糊状、多相流体、高低温流体、强酸及脉动流体进行测量。可广泛应用于石油、化工、食品、造纸、制药等行业。
The basic principle of Coriolis mass flowmeter was as follows:liquid flew a section of tube under angular oscillation(same phase oscillation)and produced coriolis force on the tube,the force value direct proportional to mass flow of liquid,torsional oscillation(reverse oscillation)superposed on the tube and the angle of torsion also direct proportional to mass flow of liquid.The mass flowmeter was invented in1980's,and only a few countries could produce it today such as United States,German,Japan,Britain and Denmark etc.The mass flowmeter could be used in petroleum industry,chemical industry,food industry and pharmaceutical industry to slurry liquid,multiphase liquid,high temperature liquid,strong acid and pulsing liquid etc.(Tran.by YUE Yang)
