Series 3000 MVD Transmitters and Controllers
Using Totalizers and Inventories
In addition, if the custody transfer application is installed and World Area is set to OIML, the process
totalizers and inventories are replaced by the following:
• Transfer totalizers – track the total quantity of the transfer variable measured by a single
custody transfer transaction. They are automatically reset when the custody transfer
transaction ends.
• Transfer inventories – track the total quantity of the transfer variable measured across custody
transfer transactions. They cannot be reset.
For more information on transfer totalizers and transfer inventories, see Section 19.5.6.
Note: The transmitter can store totalizer and inventory values up to 2
64
. Values larger than this cause
the internal totalizer to go into overflow.
20.3 Totalizer management
The method used to manage totalizers depends on the totalizer type and the function to be performed.
See Table 20-1.
Totalizers appear on the process monitor only if the process monitor has been configured to display
them (see Section 12.3). The user-specified label will be used (see Section 12.4). For information on
using the process monitor to reset totalizers, see Section 17.4.
Refer to Chapter 4 for information on accessing the View menu and the Maintenance menu.
