Select one of the control options defined in Table 11-2.

ED net mass flow

• Net mass flow rate
• Net mass flow is available only if the enhanced density application software is 

installed and configured to indicate net mass flow. See the enhanced density 
manual.

ED net vol flow

• Net volume flow rate at reference temperature
• Net volume flow is available only if the enhanced density application software is 

installed and configured to indicate net volume flow. See the enhanced density 
manual.

API temperature- 
corrected volume 
flow

(4)

• Volume flow adjusted by the calculated volume correction factor
• Available only if the petroleum measurement application is installed. See 

(1) Displayed only if Volume Flow Type is set to Liquid. See Section 7.3.2.
(2) Displayed only if Volume Flow Type is set to Gas Standard. See Section 7.3.2.
(3) Displayed only if the enhanced density application is installed.
(4) Displayed only if the petroleum measurement application is installed.

Enable batch

Yes

• Select Yes to enable the discrete batch application.
• Select No to disable the discrete batch application. The operation mode will 

default to the process monitor.

• If the custody transfer application is installed, with either World Area set to 

NTEP or World Area set to OIML with batching approved (see Chapter 14), 
Enable Batch is set to Yes and cannot be changed.

Time out

10.0 sec

• The Time Out period specifies how long the batch controller will wait before 

posting an alarm if flow stops or the batch totalizer or batch flow is inhibited 
while a batch is running.

• Enter a value of 0.0 to 300.0.
• Time Out is disabled if set to 0.0 seconds.
• A discrete output can be configured to activate if the Time Out period expires. 

No. of stages

1

Enter a value of 1 for 1-stage batch control, or 2 for 2-stage batch control. See 
the discussion in Section 11.5.1.

No. of decimals

1

• Enter a value of 0 to 5.
• This value specifies the number of digits to the right of the decimal point on the 

operation screen.

Reset on start

No

• If set to Yes, the batch totalizer resets when the operator starts the batch.
• If set to No, the operator must press RESET before starting a new batch
• Reset and Start can be assigned to discrete inputs or discrete events. See 

• If the custody transfer application is installed, Reset on Start is set to No and 

cannot be changed if either of the following is true: World Area is set to NTEP, 
or World Area is set to OIML and the discrete batch application is approved.
