3. Selection reference for electromagnetic flowmeter electrodes under different fluid media

The selection of electromagnetic flowmeter electrodes should be comprehensively selected based on the corrosiveness, wear resistance, and working conditions of the fluid medium. Common electrode materials and applicable scenarios are as follows

1. 316L stainless steel electrodes are suitable for media such as water, sewage, inorganic acids (such as dilute sulfuric acid and phosphoric acid), organic acids (such as acetic acid), and other slightly corrosive media.. Features: Low cost, strong resistance

2. Suitable media for Hastelloy B (HB) electrodes: all concentrations of non oxidizing acids such as hydrochloric acid (below boiling point), sulfuric acid, phosphoric acid, hydrofluoric acid, etc. Alkali solution, non oxidizing salt solution (such as sodium chloride solution). Characteristics: It has strong corrosion resistance to non oxidizing media, but is not suitable for media containing oxidants (such as nitric acid). Typical scenarios: Hydrochloric acid production, hydrometallurgy (such as gold leaching), hydrochloric acid transportation in chlor alkali industry

3. Hastelloy C (HC) electrode suitable medium: oxidizing acid: nitric acid, mixed acid (such as aqua regia), chromic acid and sulfuric acid mixture. Oxidizing salts: containing Fe3? 、 Cu2? Solution, high-temperature hypochlorite solution, seawater. Characteristics: Resistant to oxidative corrosion, but not suitable for reducing acids (such as hydrochloric acid) or non oxidizing macro preparation media. Typical scenarios: nitric acid production, metal surface treatment (such as electroplating solution), marine environment monitoring

4. Titanium (Ti) electrode suitable media: seawater, chloride solution, hypochlorite, oxidizing acid (such as fuming nitric acid). Organic acids and alkaline solutions. Limitation: Not resistant to pure reducing acids (such as concentrated sulfuric acid, hydrochloric acid), but if the acid contains oxidants (such as nitric acid), the corrosion
