Selecting the correct lining material for an electromagnetic flow meter is critical for ensuring long-term measurement accuracy, corrosion resistance, and equipment lifespan. Different industrial applications — from wastewater treatment to chemical processing and mining slurry measurement — require different lining materials based on temperature, pressure, corrosion level, and abrasion resistance.
At Pokcenser, we help industrial users choose the most suitable electromagnetic flow meter configuration for harsh operating environments, improving reliability while reducing maintenance costs.
The lining inside an electromagnetic flow meter directly contacts the measured liquid. A poor lining choice may lead to:
Corrosion damage
Reduced measurement accuracy
Premature sensor failure
Frequent maintenance downtime
Increased operating costs
Choosing the proper lining material ensures stable performance even under aggressive chemical, abrasive slurry, or high-temperature conditions.
Good aging resistance
Moderate acid and alkali resistance
Excellent elasticity
Economical and cost-effective

PTFE and PFA are the most commonly used lining materials for highly corrosive acids and alkalis because of their excellent chemical resistance.
Polyurethane rubber and ceramic linings are ideal for slurry applications due to their superior abrasion resistance.
Yes. PTFE can typically operate between -200°C and +260°C, making it suitable for high-temperature chemical applications.
For highly abrasive or corrosive applications, ceramic lining significantly extends service life and reduces maintenance costs, making it cost-effective over time.
You should evaluate:
Medium composition
Corrosiveness
Temperature
Pressure
Presence of solid particles
Installation environment
Professional selection support from suppliers like Pokcenser can help ensure optimal performance.
