Level Gauge Connection: Temperature Range -20°C to 200°C

Component Specifications

Definition

The Level Gauge Connection is a critical interface component designed to securely mount and seal level measurement instruments (gauges) to feedwater tanks in industrial storage sections. It ensures accurate transmission of liquid level data while maintaining system integrity under varying pressure and temperature conditions.

Working Principle

Provides a sealed mechanical interface between the level gauge and tank wall, allowing the gauge to measure liquid height through direct contact or sensor transmission while preventing leaks and maintaining pressure integrity.

Materials

Stainless Steel 316L (ASTM A240), Carbon Steel A106 Grade B, or Brass C36000; Seals: EPDM or Viton gaskets; Pressure rating: 150-600 PSI; Temperature range: -20°C to 200°C

Frequently Asked Questions

What are the main types of level gauge connections?

Flanged connections (ANSI/ASME standard) for high-pressure applications and threaded connections (NPT/BSP) for general industrial use.

How do I select the right material for my application?

Choose stainless steel for corrosive environments, carbon steel for general industrial use, and brass for lower pressure applications. Consider fluid compatibility and temperature requirements.

What maintenance is required for level gauge connections?

Regular inspection for leaks, gasket replacement every 2-3 years, torque verification on bolts, and cleaning of connection surfaces during gauge calibration.
