Main

Tank Name

Name of the tank record.

Override

This field indicates whether or not a tank override is in effect for this record.

Tank Number

Number of the tank.

Product Type

Product type currently contained in the tank.

Current State

The current state of the tank.

Tank Direction

This provides information about what is happening inside the tank. It can be behaving in one of the following ways:

• Filling

• Emptying

• Unknown

• Stationary

• Idle

External Flow

The external flow information provides an indication of which way the liquid in the tank should be flowing, which gives you an indication if there is anything going wrong. This information is received from devices external to the tank. Possible values include:

• Inactive — The tank is not flowing in either direction.

• Receiving — The tank is receiving product from the outside.

• Delivering — The tank is delivering product to the outside.

• Floating — The tank is potentially delivering and receiving at the same time.

• Unknown — There are no external devices configured for external flow, or there was an error getting the readings.

  Note: The Tank Direction and External Flow are calculated differently. However, they should generally be in agreement.

Alarm Inhibit

This field indicates whether or not alarms are inhibited for the tank. For more information, see Enable and configure tank alarms.

Density

The source of the density and/or gravity used to correct the volume to American Petroleum Institute (API) standards.

Units

The units by which the density is measured. This is configured in the unit profile.

Observed

The telemetered or manually entered density. This field will report N/A if there is only a corrected volume to report.

Your Administrator has two Density Source options: From product table (corrected) or From telemetry, which can then be marked as Density Corrected. If they have selected either setting, only a corrected density will be reported.

Corrected

The corrected gravity value used to correct the volume to API standards.

Override

This field indicates whether or not the density is a manually entered value.

Temperature

Units

The units by which the temperature is measured. This is configured in the unit profile.

Current (Temp)

The current temperature in the tank.

Correct Factor

The temperature correction factor.

Override (Temp)

This field indicates whether or not the temperature is a manually entered value. For more information, see Open the Tank Manual Overrides dialog.

Level

Current (Level)

The current uncorrected level in the tank from the field. This level is converted to an uncorrected volume using a volume conversion table (strapping table).

Max Allowed

The maximum safe level for the liquid in the tank.

Remain

The distance between the current fill level and the maximum safe fill level. This distance decreases as the tank fills, and increases as the tank empties.

Snowload

The snow load factor used to compensate for the effect of the roof on the volume of the tank.

Level Format

The level fraction format used to display all Level values in the tank ezXOS displays, alarm limits, and alarm messages.

Volumes

Units

Displays which units the volume values are displayed in. These values are defined by the unit profile.

Current GOV

The Gross Observed Volume (GOV) of product in the tank. The GOV is calculated by converting the tank level via a volume conversion table (strapping table).

Current Gross Standard Volume (GSV)

The indicated volume corrected to standard temperature and pressure.

GOV to Pump

The volume of liquid in a tank, excluding the tank bottom volume. The configured tank bottom volume (gross standard or indicated depending on the tank type) is subtracted from the current gross standard/indicated volume to calculate the volume of liquid that can be safely pumped from the tank.

GOV to Fill

The volume of space remaining in the tank. The current standard/indicated volume in the tank is subtracted from the configured maximum safe tank volume to calculate the volume to fill. If the volume in the tank is larger than the maximum safe volume, the volume to fill is negative.

Max GOV

The maximum volume that can be safely held in the tank.

Min GOV

The minimum volume that can be safely held in the tank.

Percent Full

The percent amount by which the tank is full.

Time to Empty/Fill

The time that it should take to fill or empty the tank at the current flow rate.

ETA (Volume)

The estimated time at which the full or empty level will be reached. The ETA is displayed as the date and time of day in MM/DD/YY hh:mm:ss format.

GSV Change

The resettable GSV counter.

Flow Rate

Units

Units that the flow rate is measured in. The units are defined by the unit profile.

GOV

GOV flow rate. The flow rate based on the tank level change.

GSV

GSV flow rate. The GOV flow rate corrected to standard temperature.

Avg GOV

Average GOV flow rate. The average flow rate based on the tank level change.

Avg GSV

Average GSV flow rate. The average GOV flow rate corrected to standard temperature.

Smoothed GOV

Smoothed GOV flow rate. The GOV flow rate where exponential smoothing is applied to filter out noise in the flow.

Smoothed GSV

Smoothed GSV flow rate. The smoothed GOV Flow Rate corrected to standard temperature.

Countdown

For more information, see Countdown.

Tank Idle

This field indicates whether or not the tank’s defined comparisons have succeeded.

Operator Idle

This field indicates whether or not you have manually forced the tank into the idle state.

Creep Level

The base level for Creep Alarm checking.

Icons

Event Summary

This is a list of all events associated with the pump and underlying status or multistate point. If the status or multistate record is not configured, this is a list of all events associated with the pump point.

Point Alarm Summary

This is a list of all current alarms associated with the underlying status or multistate point. If the status or multistate record is not configured, this is a list of all alarms associated with the pump point.

Priority Display

Opens the associated priority display. For more information about the priority display, refer to the AVEVA Enterprise SCADA HMI Administrator documentation.

Verification Control

Opens the Point Verification Control dialog. This allows you to enter Point to Point Verification results, create pending or approved verification records, and save the results to the CRM database.
