Tank Components with Negative Reconciled Values or Values Greater Than 1

This analysis rule includes the list of tank elements with reconciled component results that are negative or greater than 1. When the reconciled value is negative or is greater than 1, normal operating parameters have been violated. While nothing may be wrong (for example, the tank is being serviced) this situation is a gross error. This condition can indicate the following:

  • Missing data
  • Bad data
  • Invalid tank configuration

The following table lists a sample log output for this analysis.

Analysis Method​

  1. Collect a list of all tank elements in the current Case that satisfy the following criteria:
  • Status Attribute value is IS (In Service).
  1. Test the reconciled component value to determine if negative or greater than 1 Write to the log section of the case. Report the violating tank information.

Configuration Using the Wizard​

The configuration of the Tank components with negative reconciled values or greater than 1 is a selection of the General Gross Error Analysis Rule. You open the window for configuring the test (shown in the following figure) from the General Gross Error Analysis Rule Wizard.

  1. Open the Gross Error Configuration window as described in Configuring - General Gross Error Analysis Rule.

  2. On the Tanks tab, select Tanks with components with negative reconciled values or greater than 1.

    A Tanks with components with negative reconciled values or greater than 1 - Attributes window opens.Figure 431: Tanks with components with negative reconciled values or greater than 1 - Attributes window

  3. Select the Attributes according to the following table:

    Attributes

    SelectionsDescription
    Reconciled Component ResultsTank Attribute containing reconciled component results. The default is 'SolidComponentData'.
    StatusTank in/out of service status. The default is to 'ObjectStatus'.

  4. Click OK to finish the configuration.

    The text "CONFIGURED" displays next to the 'Tanks with components with negative reconciled values or greater than 1' selection.
