Flat Glass Liquid Level Gauges

Low, Medium, and High Pressure flat glass gauges available in reflex and transparent styles.

1. Models RHR and THR High Pressure Flat Glass Gauges
  • Reliable, easy to understand level reference.
  • Gives users the ability to inspect liquid characteristics visually (transparent style).
  • Non-intrusive
  • Operation is independent of most liquid characteristics. Multiple liquids can be processed through the same vessel without concerns for density, surface turbulence, dielectric conductivity etc.
  • No electrical power required. Provide accurate direct liquid level measurement in remote locations where power is not available. Not affected by power failures.
  • Suitable for full vacuum applications.
  • Up to a 4-section size 9 (60.875” of visible range).
  • Optional offshore coating ideal cost-effective solution for corrosive offshore environments.
  • NACE materials available (316SS only)
  • Used for verification of other level instrument technology.
  • Optional shields available to prolong glass life in corrosive environments (transparent style only).
  • High pressure design to allow for maximum pressure regardless of glass size.
  • Recessed gasket seat in chamber and cover.
