How to choose the right electrodes for different media
Typically, selection guides are included in the catalogs for electromagnetic flowmeters, and you can refer to them for guidance. Additionally, there are only a few types of electrode materials available for electromagnetic flowmeters; it is sufficient to choose the appropriate one based on the corrosion properties of the medium being measured and the corrosion resistance of the electrode material.
For pipelines carrying alkaline media with a pH above 9, which electrode is more suitable?
Considering corrosion and wear, 316L electrodes are generally the minimum standard for use with water; if a better quality electrode is desired, options such as HC alloys, titanium electrodes, or tantalum electrodes can be chosen.
I understand, thank you for your reply.
