Tanks with Corrected Measurement

This analysis rule includes the list of tank elements with the manual adjustment value set to True. Setting this flag to True causes Sigmafine to use the corrected value instead of the measured value.

Using the corrected value indicates the following:

  • Missing 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).
  • The manual adjustment value is set to True.
  1. Based on the analysis basis selection, mass or volume, collect the measured and corrected values for comparison.
  2. Write to the log section of the case. Report the violating tank information.

Configuration Using the Wizard​

The configuration of the Tanks with corrected measurements 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. Select the measurement basis.

  3. On the Tanks tab, select Tanks with corrected measurements.

    A Tanks with corrected measurements - Attributes window opens.Figure 384: Tanks with corrected measurements - Attributes window

  4. Select Attributes for the following; Measured value, Corrected value, Manual Adjustment Flag and Object In-Service, according to the following table:

    Attributes

    SelectionsDescription
    Measurement BasisSelect either mass or volume basis.
    MeasuredTank inventory actual measurement. The default is 'MeasuredMass' or 'NetVolume' depending on mass or volume selection.
    CorrectedTank inventory corrected measurement. The default is 'CorrectedMass' or 'CorrectedVolume' depending on mass or volume selection.
    Manual FlagFlag to indicate if a corrected measurement was used for the tank inventory. The default is to 'ManualAdjustmentFlag'.
    StatusTank in/out of service status. The default is to 'ObjectStatus'.

  5. Click OK to finish the configuration.

    The text "CONFIGURED" displays next to the 'Tanks with corrected measurements' selection.
