How to choose electromagnetic flowmeter electrode materials? 316L vs Hastelloy electrodes comparison

Electromagnetic flowmeter electrode selection is critical for measurement stability and instrument lifespan. Ecolor's LGF series offers multiple electrode materials for diverse application requirements.

• 316L Stainless Steel Electrodes: Standard configuration for general water applications and mildly corrosive media, cost-effective with good temperature resistance, suitable for most industrial processes
• Hastelloy C Electrodes: Designed for highly corrosive media including hydrochloric acid, sulfuric acid, exceptional corrosion resistance, extended service life in chemical industry harsh environments
• Tantalum Electrodes: Superior corrosion resistance for nearly all corrosive media, higher cost but ideal for special applications requiring maximum durability
• Platinum Electrodes: Optimal for wastewater treatment and low-conductivity media, excellent anti-fouling properties

Selection criteria include media corrosiveness, conductivity, temperature, and economic considerations. Choose 316L for general industrial water, Hastelloy for chemical processes, ensuring reliable electromagnetic flowmeter performance.
