Housing: made of ferromagnetic material application, is a housing allocation system excitation coil electromagnetic flowmeter POMDC manufacturers, and isolate the external magnetic field interference. Lining: measuring conduit and the inner side of the flange sealing surface, a layer of an electrically insulating liner intact. It is in direct contact with the measured liquid electromagnetic flowmeter POMDC sales, its role is to increase the corrosion resistance of the conduit measured electromagnetic flowmeter POMDC distribution, prevent EMF measuring metal duct wall is short-circuited. Lining material more resistant to corrosion, high temperature, wear-resistant PTFE plastic, ceramics. 3. electrochemical polarization potential interference. Electrochemical polarization potential interference is due to differences in bipolar electrode polarity induced electromotive force caused by electrolyte polarization generated on the electrode surface. Although the use of positive-negative alternating excitation magnetic field can significantly weaken the polarization potential of the order of magnitude, but not essentially completely eliminate polarization potential interference. Its properties on the nature of the fluid medium, the nature of the electrode material, dimensions related to the shape of the electrodes, with slowly varying electromagnetic flowmeter POMDC, small magnitude and other characteristics, fluid electrochemical potential interference and their solutions. So choose a suitable electrode material (such as tungsten carbide), to design the best shape of the electrodes is an effective way to reduce the size of the polarization potential; other uses alternating positive and negative poles of the rectangular wave excitation synchronous technology with microprocessor wide pulse sampling technique to use microprocessor computing functions sampled twice before subtracting eliminate traffic signal potential of polarization potential interference.
