8. Common Problems Solved with Sentry Sampling Systems

9. Problem #1: Non-constant Flow to Analyzers
Sentry VREL and BPR/RV in Tandem
VREL Reduces Bulk of Pressure
BPR/RV Does Fine Pressure Control
Shock Absorber- Extra Flow through BPR/RV
Flat Flow vs. Pressure Curve

10. Problem #2: Poor Sample Temperature Control
Competitor’s Bath Systems are not “Isothermal”
Competitor’s Bath Systems typically only cool
Bath has Poor Approach Temperature due to Low Turbulence
Sentry System uses Dedicated Secondary Coolers
High Surface Area- Close Approach Temperature
+/ C control with Chiller; 25+/- 0.5 C through Sentry Coolers

11. Problem #3: Plugging Sample Lines
Typically caused by Oversized Sample Lines
Also Caused by Low Flow
Sentry Properly Sizes Coolers with Cooler Program
Sentry Recommends Low Pressure Blowdown

12. Problem #4: Samples Too Hot
Many Times Competitor’s Coolers are Undersized
Computer Sizing Can Eliminate
Sentry has over 30 Cooler Models, Competitors have 2 to 4 models
Sentry models include 0.11, 0.16, 0.22, 0.33, & 0.44 Square Meter Surface Area

13. Problem #5: Rusting/Patched Panel Front
Most Competitor’s Panels have Painted Carbon Steel Fronts
Sentry Panel has Corrosion Resistant Modular 304 SS Front
Modular Front Allows Future Changes Without Patching the Panel Front

14. Problem #6: Too Low Sample Flow
Competitor’s Don’t Size Coolers Properly
Steam Samples, Especially Low Pressure Steam, Needs High Capacity Sample Cooler
Sentry has Special High Surface Area/Low Pressure Drop Coolers- FLF-6222/FXF-6223

15. Problem #7: Thermal Excursions
Thermal excursions can cause operator injury, damage cells, analyzers and other components and discharge of steam to atmosphere
Thermal excursions can be caused by loss of cooling water, high sample flow rate, fouled or plugged sample cooler or high cooling water temperature
Thermal Shut Off Valves - requires no pneumatic or electrical power, re-settable latching design, positive position indication, compact package
Optional switch for remote indication

16. Problem #8: Multiple Independent Analyzers
Calibration differences can occur between independent analyzers
Calibration requires valuable time
Sharing one analyzer reduces calibration differences, calibration time, consumable usage, capital cost
Sentry Sequencer is a proven method of analyzer sharing

17. Kinds of Projects Complete Turnkey Panel Upgrade with Components
Some Local Content- Conditioning by Sentry/Analyzers Supplied Locally

18. Get Sentry Specified Sentry Panel Specification
Specify Sentry Components
Require Dedicated Secondary Coolers
Require Flanged, single gasket, 304 SS shell, 304 SS Bolts, and 316 SS Tubing
Require Sentry VREL on High Pressure Lines (> 35 Barg)
Require Sentry TSV & BPR/RV
