Introduction to the principle of electromagnetic flowmeter selection

Principle of electromagnetic flowmeter selection
(1) Whether the measured medium is a conductive liquid or slurry, thereby determining whether an electromagnetic flow meter is selected;
(2) The conductivity of the measured medium determines whether the type of electromagnetic flowmeter is high conductivity or low conductivity;
(3) The nominal diameter of the maximum, minimum and common flow process piping required by the process determines whether the flow rate of the medium is at a more economical flow point, whether the pipeline needs to be reduced, and finally determines the diameter of the flowmeter;
(4) Determine whether to adopt an integrated or split type flowmeter, and the degree of protection of the flowmeter, etc., based on the arrangement of the process piping;
(5) Select the electrode type according to whether the measured medium is easy to crystallize or crusting;
(6) selecting an electrode material according to the corrosiveness of the measured medium;
(7) The corrosiveness, wear and temperature of the measured medium determine the lining material to be used;
(8) The highest working pressure of the measured medium determines the nominal pressure of the flowmeter;
(9) The insulation of the process pipe determines the type of grounding ring
