PTFE Lined Anti-Corrosive Magnetic Level Gauge

The LEDAER PTFE Lined series is the ultimate solution for measuring highly corrosive and aggressive liquids. By integrating a seamless stainless steel outer chamber with a high-precision PTFE (Teflon), PFA, or F46 lining, we have created a sensor that combines structural steel strength with total chemical immunity. It is the gold standard for level monitoring in the presence of strong acids, alkalis, and oxidizing agents.

PTFE LINED · EXTREME CORROSION RESISTANCE

LEDAER PTFE Lined
Magnetic Level Gauge

Zero-Leak Architecture | Immune to Concentrated Acids & Alkalis

🔧 Product Details

This gauge utilizes an advanced lining process where the PTFE tube is tightly fitted to the inner wall of the stainless steel pipe. This ensures that the process medium is completely isolated from the metallic components. The magnetic float is also encapsulated in high-grade anti-corrosive materials (PTFE or PP), ensuring smooth movement and a 100% leak-proof performance. Its non-contact, magnetic coupling design provides a clear visual display without any risk of glass breakage or hazardous leaks.
