Some of the key features of SIR v3.0.1 include the following:
Support of different input data formats : SIR v3.0.1
can import different data formats such as text (*.rtf, *.doc,
*.txt), spreadsheet (Excel, Quattro Pro) and database formats
(Paradox, Access, Oracle...). A minimum amount of
information is needed to conduct an SIR analysis (i.e. product type,
date, closing dip volume (stick), gross deliveries, daily sales
in 28 days of observation). SIR v3.0.1 allows each client
to have its own import template. (example
of Excel format shown in Figure 1f.)
Fully Automated
Import Routine (Figure
2f.): For ongoing leak detection, fuel inventory
accounting data are uploaded on a daily basis. The import routine can easily be customized to suit
any client needs. During the data import process an
automated qualitative leak check is performed on each tank
system to provide early detection of moderate to large leaks (daily
flags routine Figure 3f.). In addition, an
automated refined quantitative analysis
(automated SIR run Figure
4f.), and subsequent manual review, are performed on a
subset of the sites. The subset is changed each day so that each
tank system is eventually subjected to a refined quantitative
analysis over the coarse of a month. The process is then
repeated each following month.
The daily flags routine is not expected to provide reliable detection of small
(chronic) leaks, and therefore, is not a replacement for the
detailed monthly SIR analyses.
User friendly interface: SIR v3.0.1 features a
professionally designed user interface. (Figure
5f displays SIR Automate/Analysis menu)
Graphical representation of input data: SIR v3.0.1 displays input data
graphically. The SIR operator to visually spot site activities
and changes in trends. Different symbols are used to readily
distinguish between non-receipt, receipt
(delivery), adjustment, and rejected days. Inventory data for a specific day
may be viewed by clicking
on the point on the graph. A pop-up tabular summary of the
inventory data then appears (Figure
6f. shows daily and cumulative reconciliation error graphs while
Figure 7f. shows inventory data for clicked point)
Dip Chart Calibrations: An approximate correction can be
made for tank-length errors where dips are provided in units of
volume. However, to perform a proper dip-chart calibration which
considers all types of dimensional and geometry errors, it is
necessary for dip readings to be provided in units of length.
Also, it is necessary to know the general geometry of the tank,
namely: the type of tank body (i.e., cylindrical tube, tapered
tube, or two tapered sections joined together), the type of end
caps (i.e., flat, dished, ellipsoidal or hemispherical), and if
the tank is compartmentalized. The more information that is
known about the tank, the easier it is to backcalculate the true
dip chart. The program may also scan a library of known dip
charts to find the best match (Example of dip chart
calibration screen shown in Figure 8f.)
Graphical Output: SIR v3.0.1 provides presentation-quality
graphs that show monthly and annual trends in cumulative
reconciliations errors. The detailed Results screen (Figure
9f.) presents the summary of the results from the tightness test
including the recommended actions to be taken by the tank
owner/operator (Figure 10f. shows annual cumulative graph).
Clear and concise reports: The completed reconciliation
reports (Inventory records, Detailed SIR Results and Site
Summary) may be viewed on the computer's monitor and copies of
the reports may be printed at the press of a button (click
here to see Site Summary Report displayed in Figure 11f.).
