Tank Analysis Types
The analysis type selected by the operator determines the method used to search
for a leak. When configuring a tank, the following analysis types can be set:
•Static
• Continuous
•Real-Time
Static Analysis
Note! A tank typically requires 24
hours to become stable for
adequate Static analysis.
A Static analysis type requires the tank to be shut down (out-of-service) and stable
for 24-48 hours, depending on the gauge type. Typically, a total of 24 hours of
valid data or quite time is needed to perform a relevant static tank analysis. After
analyzing valid data from ArchiveManger over a minimum 24 hour time period, the
system can report valid leak rates.
Continuous Analysis
Continuous analysis allows the operator to keep the tank in use while performing
an analysis. The system automatically identifies valid down times from
ArchiveManager during regular operation and builds the results. Continuous
analysis does analyze tanks in real-time, like Static Analysis, Continuous Analysis
are manual operations initiated by the user.
Real-Time Analysis
Real-Time analysis allows for an automatic continuous analysis of tanks. An
operator will not have to interact with the Leak Detection system to perform an
analysis. Unlike Static and Continuous types, Real-Time Analysis works
constantly to analyze the leak rate. Tests are performed automatically every day at
12:00 am. Leak Detection can, if configured, trigger an alarm if the analysis
detects a leak that is out of range. Also, an alarm is triggered if Leak Detection
detects that there is not enough quiet time data in the current month, from the tank
to produce a valid Leak Test Report.
