Appendix F - Using the Console’s Autocalibration Feature
Using the Autocalibration Feature on an FFS
Tank Gauge
Introduction
Autocal is a feature of the Colibri Tank Monitoring Systems
which generates a tank strapping chart in order to
accurately calibrate and reconcile your fuel management
system automatically. Autocal compares sale of product
from dispensers with changes in tank volume.
Autocal corrects discrepancies in delivery reporting and
daily reconciliations that are caused by inaccurate tank
information programmed into the ATG. Incorrect tank
information can come from:
• Lack of a tank chart
• Wrong tank chart
• Tank that deforms over time and no longer represents
its tank chart
Autocal Requirements
A high variance on a tank’s Daily Reconciliation Reports,
means that the amount of product flowing through the
dispensers appears to be different from the amount leaving
the tank. This could mean that the manufacturer’s tank
chart programmed into the ATG is not accurate, but it can
also be caused by several other things. The following
items should always be checked by a certified service
professional before starting Autocal:
• Autocal
cannot be performed on manifolded tanks
• Probes must be properly installed
• Tank tilt calculations must be correct (or 0 if the probe is
at tank center)
• The tank charts provided must be correct
• The tank must be programmed correctly (length,
diameter, correction points)
• Make sure that probe alarms or TS-DIM (Dispenser
Interface Module) problems are not the reason for the
Over / Short status
• Recently passed tank tests and line tests are on file
• The dispenser meters are calibrated
• Your FFS ATG has the Reconciliation option and is
interfaced with a POS / dispenser
• Your FFS ATG has the correct Reconciliation
programming
Note: Calibrating a tank with Autocal that does not meet
the above criteria could potentially cover up a
problem or leak.
Hardware and Software Requirements
An Colibri gauge must have the TS-TRAC internal
software option to perform the Autocal feature. The Colibri
Tank Monitoring System must be doing accurate dispenser
reconciliation.
Autocal Preparation
Determining Sites That May Require Autocal. The following
steps will help determine if an Autocalibration may be
necessary
1. Generate a DIM Reconciliation Report for the last
30 days. Look for tanks that have Over or Short
status on the report.
2. Take note if any days show missing sales or sales
numbers that are unrealistic. These days may
be the reason that the status may show OVER
or SHORT, but they are not reasons for using
Autocal. It is possible that the tank still needs to
be calibrated even if it has some missing days
or data. The “good” days need to be examined
to see if the Daily Variance is usually high. If the
Daily Variance is greater than 10% of the sales
on “good” days, then there is another problem in
the system that needs to be fixed prior to starting
Autocal.
