ClearGard® Flow Indicators – Saint Gobain

Applications

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

Note: Burst pressure ratings at ambient 70°F (21°C). For applications over 300°F, consult factory.

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.
