Product details

FLDC series intelligent electromagnetic flowmeter has high accuracy and stability; It is a velocity flow meter which has been widely used in many industrial fields, including chemical industry, chemical fiber, food, papermaking, sugar-making, mining and metallurgy, water supply and drainage, ambient protection, water conservancy, steel, petrochemical, oil field. It is used for volume flow measurement of all kinds of conductive fluid medium, such as all kinds of acid, alkali, salt solutions, water coal slurry, pulp, paper pulp, pulp, corn pulp, sewage, cooling raw water, salt water, all kinds of beverage and liquor.

 

In the flow measurement and control of industrial processes such as petrochemical industry and chemical fertilizer, a large number of electromagnetic flowmeters are used to solve the problem of medium corrosion. However, in the production sites of these industries, the volatile gases of explosive gases and flammable liquids exist in the air, so explosion-proof electromagnetic flow juice is needed. The most commonly used explosion-proof forms are explosion-proof and intrinsically safe.
