SECTION 1 — GENERAL INFORMATION
1.1 INTRODUCTION
In 1994, Intek Inc. introduced the
RheoVac
®
air in-leak monitor for continuously measuring condenser
air in-leakage. This monitor was the first and only instrument to measure all of the necessary fluid
properties in the condenser exhaust line to provide an accurate, reliable air in-leakage measurement:
— the
RheoVac
®
Air In-Leak Monitor*
*USPNs 5,485,754; 5,752,411
The next generation instrument, the
RheoVac SENTRY
, uses the same proven sensor configuration, but
brings new capabilities consistent with the industry’s need for local as well as centralized and remote
monitoring.
The
RheoVac
technology was developed with the help of power plant engineers, to overcome the
deficiencies of existing air in-leakage and condenser performance measurement instrumentation and to
create a powerful, complete condenser system analysis tool. No single product provides power plant
engineers with as much diagnostic information related to the condenser as the
RheoVac SENTRY
System.
In addition to providing reliable, real time indication of condenser air in-leakage, the
SENTRY
System
provides valuable information that can be used to analyze problems associated with vacuum system
components, thereby improving plant efficiency, reducing downtime and increasing maintenance
effectiveness.
1.2 BENEFITS
The following are some of the unique benefits of the
RheoVac SENTRY
System:
•
Distinguishes between air flow and water vapor flow
•
Measures exhauster capacity
•
Measures vacuum quality
•
Allows operators to distinguish between air in-leakage and pump failure
•
Continuous monitoring provides event time stamp
•
Provides high resolution, range and accuracy of data
•
Retrievable on-board data storage
•
Provides data for condenser performance diagnostics
•
Provides centralized access to the data from all of the
RheoVac
probes installed in the system
•
Provides easy access to individual probe’s data as well as on-screen review of selected
common data from all of the probes for performance analysis
•
Graphic representation of monitored data gives visual indications of performance changes
•
Provides easy review of “before” and “after” data through the diagnostics screen to evaluate
the effect of system changes
•
Portable remote measurement (optional feature) of air-in-leak changes through the use of a
hand-held display unit – used to locate leaks
