How to distinguish the medium corresponding to the electrode of an electromagnetic flowmeter?

Electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquids and slurries in closed pipelines. Includes a range of highly corrosive liquids. In addition to the lining, the parts of the electromagnetic flowmeter that are in contact with the medium are electrodes. Correct and reasonable selection of the measuring electrodes of the electromagnetic flowmeter is of great significance to extending the service life of the electromagnetic flowmeter. The following is a brief introduction to the performance of electromagnetic flowmeter electrodes for your reference.

1. Molybdenum-containing stainless steel (0Cr18Ni12Mo2Ti): resistant to nitric acid, less than 5% sulfuric acid at room temperature, boiling phosphoric acid, formic acid, alkali solution, sulfurous acid under a certain pressure, seawater, acetic acid .

2. Hastelloy C (HC)/Hastelloy B (HB): resistance to oxidizing acids, chemical salts, seawater resistance, resistance to non-oxidizing acids, non-oxidizing salts, alkali, Sulfuric acid at room temperature.

3. Titanium (Ti): resistant to seawater, various chlorides, hypohydrochloric acid, chemical acids (including fuming nitric acid), organic acids, and alkali.

4. Tantalum (Ta): resistant to other chemical media except fuming sulfuric acid and alkali, including boiling hydrochloric acid, nitric acid and sulfuric acid less than 175°C.

5. Platinum (PT): resistant to various acids, alkalis, and salts, excluding aqua regia.
