Meters with Reconciled Values Below Minimum or Above Maximum

This analysis rule includes the list of meter elements that have a reconciled value below the minimum or above the maximum. When the reconciled value falls outside the range indicated by the element's minimum and maximum, the solution is falling outside normal operating parameters and needs to be examined for further issues. This condition can indicate the following:

  • Missing data
  • Bad data
  • Invalid lineups

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

Analysis Method​

  1. Collect a list of all meter elements in the current Case that satisfy the following criteria:
  • Status Attribute value is IS (In Service).
  1. Based on the analysis basis selection, mass or volume, compare the reconciled value to the minimum and maximum attributes.
  2. Write to the log section of the case. Report the violating meter information.

Configuration Using the Wizard​

The configuration of the Meters with Reconciled Values below the Minimum or above the Maximum 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 Meters tab, select Meters with reconciled values below the minimum or above the maximum.

    A Meters with reconciled values below the minimum or above the maximum - Attributes window opens.Figure 422: Meters with reconciled values below the minimum or above the maximum - Attributes window

  3. Select the measurement basis and the Attributes according to the following table:

    Attributes

    SelectionsDescription
    Measurement BasisSelect mass or volume measurement basis for comparison.
    ReconciledMeter reconciled value. The default is 'ReconciledMass' or 'ReconciledVolume' depending on mass or volume selection.
    MinimumMeter minimum flow value. The default is 'MinimumMass' or 'MinimumLiquidVol', depending on mass or volume selection.
    MaximumMeter maximum Flow value. The default is 'MaximumMass' or 'MaximumLiquidVol', depending on mass or volume selection.
    StatusElement in/out of service status. This defaults to 'ObjectStatus'.

  4. Click OK to finish the configuration.

    The text "CONFIGURED" displays next to the 'Meters with reconciled values below the minimum or above the maximum' selection.
