Hygienic RS485 electromagnetic flowmeter is used in food processing enterprises

The structure of electromagnetic flowmeter is mainly composed of magnetic circuit system, measuring conduit, electrode, shell, lining and converter  

Magnetic circuit system: its function is to produce a uniform DC or AC magnetic field.  Dc magnetic circuit to achieve with a permanent magnet, its advantage is simple structure, the ac magnetic field interference is small, but it is easy to make by measuring the electrolyte liquid polarization in the ducts, the positive electrode is surrounded by negative ion, negative electrode is surrounded by positive ions, the electrode polarization, and lead to increased internal resistance between two electrodes, thus seriously affect the normal work of the instrument.  When the diameter of the pipe is large, the permanent magnet is correspondingly large, cumbersome and uneconomical, so the electromagnetic flowmeter generally uses alternating magnetic field, and is generated by 50HZ power supply excitation.  

Electrode: its role is to elicit and measured proportional to the induction potential signal.  Electrodes are generally made of non-magnetizing stainless steel and are required to be flush with the lining so that fluid can pass unimpeded.  Its installation position should be in the vertical direction of the pipeline, in order to prevent sediment accumulation on it and affect the measurement accuracy. 

Lining: a complete electrical insulating lining is provided on the inside of the measuring tube and on the flange sealing surface.  It is in direct contact with the measured liquid and its role is to increase the corrosion resistance of the measuring catheter and prevent the induction potential from being short-circuited by the wall of the metal measuring catheter.  Lining material is corrosion-resistant, high-temperature resistant, wear-resisting polytetrafluoroethylene plastic, ceramics and so on.
