How to select electromagnetic flowmeters for corrosive media? What corrosion-resistant materials are available?

Electromagnetic flowmeter selection guide for corrosive media applications

Corrosive media electromagnetic flowmeter selection focuses on proper electrode materials and liner choices. Ecolor's LGF series offers comprehensive corrosion-resistant configurations.

  • Electrode Materials: 316L stainless steel (general corrosion), Hastelloy C (strong acids/alkalis), Tantalum (hydrofluoric acid), Platinum (aqua regia)
  • Liner Materials: PTFE/PFA lining (chemical stability), Ceramic lining (wear/corrosion resistance), Rubber lining (mild corrosion)
  • Typical Applications: Sulfuric acid, hydrochloric acid, sodium hydroxide, sodium hypochlorite measurement
  • Protection Grade: IP68 protection for harsh corrosive environments

For severe corrosion applications, remote electromagnetic flowmeters keep converters away from corrosive sites. Ultrasonic flowmeters with clamp-on installation avoid media contact, ideal for corrosive media measurement.
