Low pressure flat glass gages in reflex and transparent styles


  • 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.
  • Provide a near-unlimited length of measure.
  • Optional offshore coating 2600 protection; ideal cost-effective solution for corrosive offshore environments.
  • NACE wetted materials available for sour gas service.
  • Used for verification of other level instrument technology.
  • Standard flat gasket seat allows easy removal of gasket residue during rebuild.
  • Optional shields available to prolong glass life in corrosive environments (transparent style only).
