Electromagnetic Flowmeter on How to Choose the Lining？

Electromagnetic flowmeter lining material should be selected according to the measured medium itself corrosive, temperature and abrasive.

• Ordinary Rubber

Medium temperature of 60 ℃, for corrosive waste water or non-corrosive conductive liquid measurement, generally used in urban water supply and drainage and other fields.

• Polyurethane

Has excellent abrasion resistance, but poor corrosion resistance, and the temperature must not exceed 80 ℃. Generally used in industrial and mining environments that require high wear resistance, such as mineral slurry coal slurry and other media measurement.

• Polytetrafluoroethylene, PTFE (F4)

One of the more commonly used lining materials, with excellent corrosion resistance, general temperature resistance of up to 120 ℃, measuring a variety of acidic and alkaline media is preferred. So generally used for sanitary liquids or strongly corrosive liquids, such as concentrated acids and alkalis.

• PFA

 PFA lining has strong corrosion resistance, temperature resistance up to 200 ℃, Commonly used in the food, beverage and pharmaceutical industries where strict hygiene is required.

• Neoprene

Excellent elasticity, high tearing force, and good wear resistance. Resistant to erosion by general low-concentration acid, alkali and salt solutions, but not resistant to corrosion by oxidizing media <80°C; Measuring water, sewage, mud and mineral slurry.

• Ceramic Lining

It is the best lining material, the disadvantage is that the production process requires high, expensive.
