Using the Gas Analysis Data View

Use the Gas Analysis data view to view, and edit* imported gas analysis records for a single selected gas device Node (gas meter, station meter, or chromatograph). Gas analysis data is displayed for one Gas Device Node at a time (liquid device Nodes are not supported). Because each Node is associated with a variety of gas analysis values that impact the calculation of its measurement data (depending on the Node type and its specific circumstances), any changes made to these gas analysis details are tracked and audited by the FMS service. See CygNet Measurement Data Calculation for more information about recalculation implications of editing base condition values (base temperature or base pressure) or heating value basis.

*Note: Editing functionality is only available in systems licensed for FULL mode.

The records are always filtered by date, with the oldest record shown first. You can filter the type of gas analysis records viewed in the control by selecting to configure and use a filter via the control toolbar. See Configure filter on the control toolbar for more information.

Each row of the grid displays a single gas analysis record. Each column represents a category of data. The control toolbar and the context menu provide additional options to manage files and edit or view associated gas analysis entries.

When there are multiple entries in the gas analysis grid, the top row displays the last record prior to the current time window. In that case, the top row is locked and cannot be edited. You can double-click any editable cell to edit gas analysis item values directly from the control, or you can right-click an entry row to access options to view or edit gas analysis entries for the selected record.

Columns

A variety of data fields are available to be viewed in the grid columns of the gas analysis view. When you open a new Gas analysis view in the Configuration control, a default set of column headers is displayed. You can modify the default set by adding/removing desired data fields, and by reorganizing the column locations.

Columns can be reorganized for the most efficient viewing of data in the following ways.

The Effective Date/Time column is always displayed, and cannot be removed. It is the column used for sorting, which is indicated by an up arrow in the column header box.

Default Columns

The following columns are displayed by default when you create a new Configuration control and select the Gas analysis view.

Default Gas Analysis Column Description

Effective Date/Time (t)

Lists the effective date and time for the selected gas analysis record, followed by the time format (t) indicated as (D) Device, (C) Contract, or (L) Local.

Note: The grid is always sorted by date and time, therefore the Effective Date/Time (t) column cannot be removed. It can be repositioned within the grid however.

Sample Date

Lists the sample date

Data Source

Lists the data source for the selected gas analysis entry.

Possible values are as follows.

  • Linked Gas Quality - display data from a linked gas quality source
  • System Generated - displays data system-generated by the calculation engine
  • User Entered - displays user-entered data that did not trigger a recalculation, and did not modify the value for Volume, Mass, or Energy
  • User File - displays data from user-generated files

Status

Lists the status of the gas quality data send action.

Possible values are as follows.

  • Timeout
  • Failed
  • Succeeded
  • Pending
  • Review*

*Notes:

The "Review" state appears when gas analysis samples fail validation thereby generating exceptions. Analyst review and action is then required before the sample data can be used.

In Review state, when all exceptions are ignored or fixed to promote the record, the system automatically updates the record's Status value from Review to Pending so that the data is available for use.

See Using the Exceptions Control for more information about handling exceptions.

Right-click on a selected record to access the context menu, and then click Edit to change the selected gas analysis record via the Edit Gas Analysis Entry dialog box.

Note: You can also double-click the row header to display the detailed dialog box to make edits.

See Viewing or Editing Gas Analysis Entries for more information.

Shading

Define shading behavior.

Right-click in the white space of the grid to access the context menu, and then click Shading to access display options. The selection determines which of the specified elements will have shading colors applied.

Options are as follows.

  • None
  • Both
  • Foreground
  • Background

Default value is Both

Use the Shading colors option to select what colors to apply to the selected elements.

Shading colors

Define shading colors.

Right-click in the white space of the grid to access the context menu, and then click Shading colors to access the Shading Colors dialog box to select Foreground (text) and Background (cell) colors, from the drop-down menus, to apply to the grid.

Options are as follows.

  • Default - color values that will appear if not configured otherwise
  • [Palette] - a range of preset selections
  • Other - a broad range of Standard or Custom colors from which you can select

A preview of the selected shading colors appears on the dialog box, so you can review your selections prior to clicking OK.

Use the Shading option to select what grid elements will have the selected color(s) applied.

See Customizing Shading Colors below this table for more information.

Define how many decimals to display in the grid.

Right-click anywhere in the grid to access the context menu, and then click Decimal precision to access options for the grid display. Click the desired option, from 0 - 10 decimal places.

Default value is 7

Approve

Approves the selected gas analysis record. This option is made available only when the Status value for the selected record equals "Review" (sample failed validation).

Right-click on a selected record with a "Review" status value to access the context menu, and then click Approve to accept the sample record . This changes the status value to "Pending" and clears any associated exceptions.

Taking this action also accesses the Save Changes dialog box to generate a record of the change. See Viewing or Editing Gas Analysis Entries for more information.

*Notes:

Be certain of an Approve action, as it permanently retains the sample record to become available for use in your system. There is NO "undo" for this action.

Approved records can be edited, causing data recalculations to occur when the Save action is taken.

Reject

Reject the selected gas analysis record. This option is made available only when the Status value for the selected record equals "Review" (sample failed validation).

Right-click on a selected record with a "Review" status value to access the context menu, and then click Reject to reject the sample record and remove the entry from the list.

*Notes:

Be certain of a Reject action, as it permanently removes the sample record from availability for use in your system. There is NO "undo" for this action.

Rejected records are retained in the database or archives and can only be retrieved via FMS reports.

Associated exceptions are cleared automatically when the gas analysis record that generated them is rejected.

Send gas quality to device

Run a Send Gas Quality command to send updated gas quality data based on the selected gas analysis record.

Right-click on a selected record to access the context menu, and then click Send gas quality to device to run a Send Gas Quality command for the selected Node. A dialog box will appear, to verify that you want to send GQ data from the selected gas analysis record directly to the device. Click Yes to execute the command.

See Send Gas Quality for more information about the command.

Customizing Shading Colors

Customize or edit the color shading shown in the grid as follows. Right-click within the grid to access the context menu options, and then select Shading Colors to adjust your selections.

To Configure Shading Colors

  1. Select Shading colors on the context menu to access the Shading Colors dialog box, where you can configure colors to use for Foreground (text) and/or Background (cell) shading on the grid.

    Shading Colors

  2. For each shading option you have selected to use, Foreground (text) and/or Background (cell), click the selector arrow to access a drop-down menu of color options that you can apply to the grid. Shading color options are as follows.

  3. Once all selections are made, click OK to save your choices.
