Electromagnetic flowmeter electrode performance

Electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquids and slurries in closed pipes. Including highly corrosive liquids such as acids, alkalis, and salts. In addition to the lining, the part of the electromagnetic flowmeter that contacts the medium is the electrode. The correct and reasonable selection of the measuring electrode 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 the electromagnetic flowmeter electrode for your reference.

1. Molybdenum-containing stainless steel (0Cr18Ni12Mo2Ti): It can withstand nitric acid, sulfuric acid less than 5% at room temperature, boiling phosphoric acid, formic acid, alkaline solution, sulfurous acid under a certain pressure, sea water, and acetic acid.

2. Hastelloy C (HC) / Hastelloy B (HB): resistant to oxidizing acids, oxidizing salts, seawater, non-oxidizing acids, non-oxidizing salts, alkalis, and sulfuric acid at room temperature.

3. Titanium (TI): resistant to seawater, various chlorides and hypochlorous acid, chlorinated acids (including fuming nitric acid), organic acids and alkalis.

4. Tantalum (Ta): Resistant to all chemical media except hydrofluoric acid, oleum and alkali, including boiling hydrochloric acid, nitric acid and sulfuric acid below 175°C.

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