Description

Applications

 

  • For monitoring product levels and movement in rigid piping systems

 

Features and Benefits

 

Ultra-Pure 
  • Chemfluor® FEP tubing material resistant to virtually all known chemicals
  • Helps maintain your ultra-pure environment
Non-Stick Surface 
  • Up to six times smoother than standard PFA tubing
  • Greatly reduces potential for cross-contamination
Superior Visual Clarity 
  • Allows accurate monitoring of product levels and movement in rigid piping systems
  • Will not discolor, resists ultraviolet light
Radial Crimp Design 
  • Utilizes PermaSeal® radial crimp fittings 
  • Excellent durability, increased pressure ratings
  • Provides a full flow smooth bore inside diameter

Flow Indicator Details

 

  • ClearGard® flow indicators are available in sizes 1/2″ up to 3″ (lengths up to 10 feet) in six standard end styles
  • Stems are manufactured from grade 316L stainless steel with an interior surface finish exceeding 15Ra or better
  • Non-metallic stems in a number of polymers are available for metal-sensitive applications
  • Can also be ordered as a homogenous unit, thus making it the smoothest internal bore flow indicator available; there are size and length limitations, however, so contact factory for availability

 

End Connector Styles

 

End Connector Styles: TE Tube End, AF Flange End, TC Sanitary Clamp, TC Step Up, EM Male I-Line, EF Female I-Line

 Pressure Correction Factors for All Non-Caged Flow Indicators 
Using operating pressure @ ambient with correction factors for elevated temperatures.
70°F 150°F 200°F 250°F 300°F
100% 65% 50% 35% 25%

Example:  1″ flow indicator @ 200°F rated @ 125 P.S.I. ambient x .50 = 62.5 P.S.I. @ 200°F.
