Application of electromagnetic flow meter & electromagnetic compatibility analysis

XIE Shi-hong1,ZHU Xiao-cong2,JIANG Li-bo1(1.College of Electric & Information Engineering,Shaanxi University of Science & Technology,Shaanxi Xi'an 710021,China;2.Department of Business Administration,Shaanxi Polytechnic Institute,Shaanxi Xianyang 712000,China)  
The paper introduced the methods of using ADMAG AE electromagnetic flow meter,and the technology of enhancing electromagnetic compatibility.Interference sources of electromagnetic flow meter mainly include electromagnetic interference,electrochemistry noise and power source voltage and frequency fluctuations.Presently,electromagnetic flow meter used dual frequency excitation technology,synchronous sampling technology,input protecting technology and grounding technology to resist interference.Practical application showed that these technologies are effective to resist interference.
