Product Description
Stable Rotary DN80 Metal Tube Rotameter Long Service Life Industrial Flow

Stable Metal Tube Rotary Flow Meter DN80 With Long Service Life

A DN80 (3-inch) metal tube rotameter is a rugged, variable-area flow meter designed for industrial environments where glass tubes are too fragile. Its all-metal construction—typically stainless steel—provides the structural integrity needed to handle high pressures, extreme temperatures, and corrosive fluids, ensuring a long service life.

Key Features for Stability & Longevity
  • Magnetic Coupling: These meters use a non-contact magnetic system to track the internal float. This eliminates the need for mechanical seals, preventing leaks and reducing wear over time.
  • Corrosion Resistance: For aggressive chemicals, you can choose models with SS316L, Titanium, or FEP/PTFE lining to prevent material degradation.
  • Mechanical Simplicity: With only one moving part (the float), there are no bearings or gears to fail, which significantly lowers maintenance requirements.
  • Stable Readings: Many industrial models include magnetic damping to minimize pointer jitter caused by rapid flow fluctuations or vibrations.
