　　3、 Selection:

　　1. Caliber selection

　　Based on the diameter of the process pipeline, pipeline pressure, and sewage flow rate provided by the sewage treatment plant, an electromagnetic flowmeter with a diameter of D-600 mm is selected, and there is no need for pipe reduction or expansion on site.

　　2. Selection of lining and electrode materials

　　Electromagnetic flow meters are mainly used to measure fluid flow rates with a conductivity of ≥ 5U S/cm. Different lining and electrode materials should be selected based on the corrosiveness, wear resistance, temperature, and condensation characteristics of the measured substance, as well as their affordability.

　　The lining materials of electromagnetic flow meters include chloroprene rubber material with moderate corrosion resistance and resistance to generally low concentrations of acids, alkalis, and salts, polyurethane rubber with strong wear resistance and moderate corrosion resistance, polytetrafluoroethylene with strong corrosion resistance and suitable for high temperatures, polytetrafluoroethylene with tensile and compressive properties equivalent to polytetrafluoroethylene, polyethylene with resistance to dilute acids, alkalis, and salts at temperatures<60 ℃, and polyphenylene sulfide at temperatures<100 ℃.
