Some of the key features of OFM include the following:


Fast and Accurate Inventory Accounting: OFM eliminates many of the tedious aspects of inventory control. The forms in the journal are designated to look like those in traditional paper documents to make the transition to OFM as easy as possible. To complete these forms the user need only enter raw dip measurements, pump readings and fuel receipt data. Figure 1f. on the right displays easiness of using OFM's Daily Inventory Form.


Fully Automated Calculations : OFM automatically checks these data as they are entered to help identify typographical errors and other common mistakes so they can easily be corrected at that time. As well, OFM will highlight any warning conditions that occur (for example, high water levels) and provide appropriate instructions for the operator as shown in Figure 2f.. In addition, OFM performs all the dip reading conversions and calculations needed to do daily, monthly and annual inventory reconciliations.


Accurate Dip Charts: OFM has built-in-library of dip charts for all the common makes and models of underground storage tanks used in Canada. This simplifies initial setup requirements for the program and helps to ensure that the proper charts are always being used.

The dip charts in OFM's library are developed based on the design dimensions and shape (or geometry) of the tanks, as reported by the manufacturer, and they use rigorous calculation algorithms. In many cases, these charts are actually more accurate then those published by manufacturer due to simplifying approximations they often make in these calculations (click here to see example shown in Figure 3f).

If the tank model is not present in OFM's library the user may enter the tank geometry and dimensions, and OFM will use its volume-calculations algorithms to develop the dip chart. If some of this information is unknown, a calibration service is provided with OFM to backcalculate the missing parameters using historical inventory data (click here to see example shown in Figure 4f).


Temperature Compensation: OFM allows the user to indicate under the location setup whether temperature compensating dispenser meters are used, then it automatically makes the necessary adjustment to the data entry forms, online help system, and reconciliation procedures (example in figure 5f.).


Graphical Output: OFM provides presentation-quality graphs that show monthly and annual trends in cumulative reconciliations errors. (click here to see example shown in Figure 6f.).


Clear and concise reports: The completed reconciliation reports 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 Monthly Summary Report displayed in Figure 7f.).


Comprehensive Context-Sensitive Online Help System: In addition to built in standard help menu OFM provides so called context-sensitive help system. Context-sensitive help means that the Help window displays content specific to the context in which the help was requested. If the user clicks the F1 button in the Password dialog box, for example, then the Help window displays help about password maintenance policy (and also displays the rest of the table of contents in case the user wants more general information - example in Figure 8f.).
