Batch Transfer Management terminology

Accumulator Reading

The Accumulator Reading provides the raw, uncorrected volume reading reported from the field.

Accept

To accept a completed ticket.

Active Batch

A volume of fungible product transferred from one location to another location. The Active Batch is the batch that is moving through the Batch Transfer location at the present time.

Active Ticket

The data from the active batch that will be saved when that ticket is cut. This provides information about the batch volume transferred over a period of time.

Alarm Reset

To reset all period alarms, select Alarm Reset.

Audit

This field indicates whether or not any field in the ticket was edited. It must be set manually. An automated audit trail is automatically generated in the Historical database, but can only be accessed by the Administrator.

Auto Switch

This field indicates whether or not the automatic switching function is activated. If this feature is enabled, the Batch Transfer application automatically starts the next ticket in the pending queue when the volume to go on the active ticket reaches zero.

Batch

A volume of fungible product transferred from one location to another location.

Batch Counter Information

The Batch Transfer Counters displays periodic (hourly, daily, weekly, monthly, and yearly) throughput data for a current ticket or the same data summed for every ticket. These counters cannot be reset by you. The current counters are reset automatically each time a new ticket is started.

Batch ID

Identifier for a batch.

By default, Batch IDs must adhere to the following standards:

• They must begin with a letter.

• They must be no more than 31 characters in length.

• The only special characters permitted in the batch ID are the hyphen (-) and the underscore (_).

  If the Batch ID fails to meet these standards, an error message appears The standards for batch IDs can be configured by the Administrator and may be different on your system.

Batch Schedule

Contains all of the tickets. This is a table located in the Historical database. Items can be added/edited/removed to/from the batch schedule through both third-party and AVEVA Enterprise SCADA applications by accessing the stored procedures provided with the Batch Transfer installation.

Batch Transfer

The owner of all of the tickets, pending, active, and completed, for a source or set of sources. It handles everything to do with ticket management and accumulating volume.

Batch Transfer Template

The default values used to initially populate a new Batch Transfer Pending Ticket. This template can be created by the Administrator.

BatchXfer

The name as it appears in short-form on the Advanced Database Editor (ADE) and easy eXtended Operator Station (ezXOS) windows.

Completed Ticket

Completed tickets are automatically sent to the Historical database. The most recent completed ticket remains cached in RealTime. Completed tickets can be edited, and an automated audit trail will be generated. This applies both to normal tickets and to remote tickets.

Contaminated

This field indicates whether or not the ticket was flagged as contaminated. Indicates a mixing of products that may make sample impure or unsuitable.

Current GSV

Current volume corrected to standard temperature and pressure

Cut Type

Indicates the point in the interface between two batches at which the system declares the detected interface.

Mid — the detected interface is declared at the midpoint of the interface between the current batch and the next batch

Head — the detected interface is declared at the beginning of the interface between the current batch and the next batch.

Tail — the detected interface is declared at the end of the interface between the current and the next batch.

Density (weighted average)

The volume weighted average density.

Device

A device is anything that counts volume, usually a child of a source. Some examples of RealTime database (RTDB) records that count volume are tank and rate records.

Device ID

The configured device ID of this device. Typically, the name of the point or its parent.

Down Counter

Counts down from the value of the Target volume (original).

Ending

The ending volume reading.

Ending (volume reading) — the current volume count.

Ending (pending ticket) — the time at which the ticket is scheduled to end.

End Time

Actual time the ticket was cut.

Est End Time

The estimated time at which the application will pump the scheduled volume of the ticket.

ETA Target

The estimated date and time at which the target volume will be reached. (The estimate is based on the flow rate shown in the Flow Rate field and the volume shown in the Target Volume field.) This target is non-editable.

Flow Rate

Amount of liquid flowing for a specified amount of time.

Group

The group to which a Batch Transfer belongs.

GS Flow Rate

The current flow rate on the Batch Transfer corrected to standard temperature and pressure.

GOV

Gross Observed Volume (GOV) — raw, uncorrected volume.

GV

Gross Volume: The Indicated Volume (IV) with Meter Correction Factor (MCF) applied but with no corrections for temperature, pressure, and density.

GSV

Gross Standard Volume (GSV) — corrected to standard temperature and pressure.

GSVolume to Go

The GSV remaining in the active batch.

IV

Indicated Volume: the raw, uncorrected volume.

Inhibit

Stops AVEVA Enterprise SCADA from generating an alarm / logs.

Inhibit Alarm

Inhibit Alarm (target volume) — inhibit alarm when the meter reaches its target volume.

Inhibit Alarm (volume) — inhibit alarm when the volume remaining before the target volume is less than the warning volume.

Inhibit Alarm (warning time 1) — to inhibit alarm when the estimated time remaining before the target volume will be reached is less than warning time.

Inhibit Alarm (warning time 2) — inhibit alarm when the estimated time remaining before the target volume will be reached is less than warning time 2.

Inhibit Log

Inhibit Log (target volume) — inhibit logging an event when the meter reaches its target volume.

Inhibit Log (volume) — inhibit logging an event when the volume remaining before the target volume is less than the warning volume.

Inhibit Log (warning time 1) — inhibit logging an event when the estimated time remaining before the target volume will be reached is less than warning time 1.

Inhibit Log (warning time 2) — inhibit logging an event when the estimated time remaining before the target volume will be reached is less than warning time 2.

Inhibit Record

Inhibits the currently selected record.

Level

Current level in a tank. The level is converted to a gross volume using a strapping table.

Maintenance Ticket

Maintenance Tickets can be used to record volume accumulation that is reported by a meter but is not intended to be accounted for as actual flow down the pipeline.

NSV

The Net Standard Volume. This provides the same information as the GSV, but with sediment and water volume removed.

Obs Density

The observed raw density reported from the field. Depending on the field device, it may be fully or partially corrected.

Obs Pressure

The raw pressure reported from the field.

Obs Temp

The raw temperature reported from the field.

Percent Complete

Indicates the percentage amount of target volume accumulated on the ticket (non-editable).

Plugin

A plugin is a small library any Developer can write that can then be used by the Batch Transfer application. In order to be a plugin, the library must implement specific functionality, such as handling data retrieval for the Batch Transfer to use. Currently, plugins can be written for Sources and Remote Ticketing.

Press Factor

The Pressure Correction Factor.

Revised

This field indicates whether or not the ticket is a revised ticket (a revised ticket cancels out a previous ticket).

Rollover

When the resettable counters reach this value, the application automatically resets the counters to zero.

Remote Ticketing

Remote Ticketing occurs when the Active Batch calculations and control of ticket completion is handled remotely by a flow computer.

Scheduled GSV

The scheduled GSV of the active batch.

Shipper

The pipeline account associated with the ticket.

Shipper ID

The shipper ID for which this meter correction factor is valid.

Source

A source is the parent of one or more devices. In some cases, it maps directly to a AVEVA Enterprise SCADA record type, such as a rate. Other times, it can map to something with many children, such as a meter with several physical meters (each physical meter would be a device). A plugin must be written for each new source type. Default sources are rate, tank, flow meter and flow computer.

Split Ticket

Splitting a ticket divides it into two consecutive tickets, and is primarily designed to allow a cutoff for month-end accounting.

Switch on Volume

When Switch on Volume is enabled, the Batch Transfer application will automatically start the next ticket in the pending queue when the volume to go on the active ticket reaches zero.

If the Manual Batch Switch has been enabled, and there is a delayed ticket start in progress, any automatic starts during the Batch Start Timeout period will be delayed until the timeout period has ended.

S&W Percentage

The ratio of sediment and water volume to the total volume, expressed as a percentage. Valid possible entries can be between 0% and 100%.

S&W Volume

The amount of sediment and water contained in the product in volume units.

Switch Status Pt

If a status point changes in a Batch Transfer, the Batch Transfer application starts a new ticket.

Target volume

This field allows you to enter the volume you wish to track. As the volume approaches the target volume, AVEVA Enterprise SCADA generates the warning alarms configured in the Warning Time: 1), Warning Time: 2), and Warning Volume fields.

Target Vol Type

This selection allows you to specify whether the volume being tracked is a gross or net volume.

Gross = Uncorrected volume (Ivolume).

Net = Corrected for temperature and pressure (GSvolume).

Ticket

A ticket is a record of a batch (or a partial batch).

Ticket ID

Identifier of a ticket.

Ticket Status

The operational status of the active ticket.

Contaminated

Contaminated tickets are typically tickets in which different product types are mixed. The contaminated flag will remain set throughout the ticket (for example, until the next ticket is started, either manually or automatically).

Total Flow Rate

The sum of the Gross Standard (GS) flow rates for all devices.

Total GS Flow

The current GS flow rate on the Batch Transfer: the indicated flow rate corrected to standard temperature and pressure.

Total GSV

The Gross Standard Volume: the indicated volume corrected to standard temperature and pressure.

Total Ind.

The uncorrected, raw flow rate.

Units

The units of the ticketed volume.

Up Counter

As volume accumulates on the new ticket, this field counts up to the value in the Target Vol field. This is non-editable.

Verify

To verify a completed ticket.

GSV to Go

The amount of scheduled volume left to pump on the current ticket.

Volume

This field allows you to enter a warning time in minutes. When the estimated time remaining before the target volume will be reached is less than this warning time, AVEVA Enterprise SCADA generates an alarm. It is possible to enter Warning Times 1 and 2.

Warning Volume

This allows you to enter a warning volume (same units as ticket). When the volume remaining before the target volume is less than this warning volume, AVEVA Enterprise SCADA generates an alarm.

WAT

The volume-Weighted Average Temperature.
