  The structure of electromagnetic flowmeter is mainly composed of magnetic circuit system,measuring duct,electrode,shell,lining and converter.
  1.The measurement is not affected by the changes of fluid density,viscosity,temperature,pressure and conductivity.
  2.There are no obstructive flow components,no pressure loss in the measuring tube,and the requirement of straight pipe section is low.It has unique adaptability to slurry measurement.
  3.Reasonable selection of sensor lining and electrode materials,that is,good corrosion resistance and wear resistance;
  4.The converter adopts a novel excitation mode with low power consumption,zero stability and high accuracy.The flow range can reach 150:1.
  5.The converter can be integrated or separated from the sensor.
  6.The converter uses 16-bit high-performance microprocessor,2x16LCD display,convenient parameter setting and reliable programming.
  7.Flowmeter is a bidirectional measurement system with three integrators:total forward,total reverse and total difference.It can display both positive and negative flow,and has a variety of outputs:current,pulse,digital communication and HART.
  8.The converter adopts surface mounting technology(SMT),which has self-inspection and self-diagnosis functions.
  9.The measurement accuracy is not affected by the changes of fluid density,viscosity,temperature,pressure and conductivity.The induction voltage signal of the sensor has a linear relationship with the average velocity of flow,so the measurement accuracy is high.
  10.There is no obstruction in the measurement pipeline,so there is no additional pressure loss;there is no movable parts in the measurement pipeline,so the sensor has a very long life.
  11.Because the induction voltage signal is formed in the whole space filled with magnetic field and is the average value on the pipeline surface,the straight pipe section needed by the sensor is shorter,and the length is five times the diameter of the pipeline.
  12.The converter adopts the latest and most advanced MCU and SMT technology in the world.It has reliable performance,high precision,low power consumption,stable zero point and convenient parameter setting.Click on Chinese to display LCD,showing cumulative flow,instantaneous flow,flow rate,flow percentage,etc.
  13.Two-way measurement system can measure forward and reverse flow.Special production technology and high-quality materials are adopted to ensure that the product performance remains stable in the long run.
