XFE series of electromagnetic flowmeter principle Profile 

 The XFE intelligent electromagnetic flowmeter measurement principle is based on Faraday's law of electromagnetic induction: conductive liquid in a magnetic field cutting the magnetic lines of force movement, the EMF generated in the conductor, the EMF E is: E = KBVD type: 
 K = -------- instrument constant 
 B = -------- magnetic induction 
 V = -------- measuring the average velocity within the pipe cross-section 
 D = -------- measure the inside diameter of the pipe cross-section 
 Thus the above equation, when the structure of the measuring tube, the magnetic flux density is constant, the volume flow rate is proportional to the EMF. Measure the induced voltage can flow into the pipe volume flow. The induced voltage signal of one or more direct contact with the electromagnetic and liquid detection, and sent through the cable converter through intelligent processing, and then the LCD display or converted into standard signals 4-20mA output of frequency signal Hartx of protocol communication . 
 Measuring the flow of conductive liquid velocity V flows through the magnetic field perpendicular to the flow direction of the flow of conductive liquid in the measuring electrode induces a voltage proportional to the average velocity, which can be drawn to the volume flow through the pipeline

 Where 

 Q -------- volume flow 
 E -------- induced voltage
