Understanding the Functionality of Reflex Gauge Glass in Industrial Applications

How Reflex Gauge Glass Works: The Science Behind Liquid Level Monitoring

Reflex gauge glass operates on fundamental optical principles to deliver precise liquid level measurements:

  • Light refraction technology‌: When liquid covers the glass surface, light reflects at 90° angles, creating visible contrast
  • Dual-layer construction‌: Features tempered outer glass with prismatic inner surface (typically 6-12mm thickness)
  • Pressure tolerance‌: Engineered to withstand up to 4,000 psi in boiler applications (ASME B31.1 compliant)

Key advantage: Provides instant visual confirmation without electrical components – critical for hazardous environments.
