Configuring Custody Transfer
14.3 Configuration options
The custody transfer application is designed to comply with three different sets of requirements, as
defined by two different regulatory agencies. Before configuring the custody transfer application,
review the descriptions below and follow the configuration instructions for the custody transfer
system that applies to you.
• National Type Evaluation Program (NTEP) – Custody transfer (NTEP) may be used on all
Series 3000 devices.
Custody transfer (NTEP) requires the discrete batch application. Only batches, as managed by
the discrete batch application, can be used for custody transfer measurement. Accordingly, the
process variable used for batch measurement (the batch flow source) serves as the transfer
variable (the process variable used for legal compliance), and the transaction is measured and
managed by the discrete batch application. See Table 14-1.
To configure custody transfer (NTEP), follow the instructions in Section 14.4.
Note: In previous versions of the Series 3000 software, this configuration type was called World Wide.
• Organisation Internationale de Métrologie Légale (OIML) – Custody transfer (OIML) and
custody transfer (OIML/batch) can be used only on Model 3500 or Model 3700 transmitters;
they are not supported on Model 3300 or Model 3350 controllers.
-In custody transfer (OIML) installations, the discrete batch application is not approved for
custody transfer use, and the transfer is used to define the custody transfer transaction.
-In custody transfer (OIML/batch) installations, the discrete batch application must be
approved for custody transfer use, and either the transfer or the batch may be used to
define the custody transfer transaction.
The enhanced density and petroleum measurement applications may or may not be approved
for custody transfer use. The options for transfer variable, transaction measurement, and
transaction management are described in Table 14-1.
To configure custody transfer (OIML) or custody transfer (OIML/batch), follow the
instructions in Section 14.5.
Note: If you are using the custody transfer (OIML) configuration (i.e., the discrete batch application
is not approved), you can still install and use the discrete batch application to run batches that are
not custody transfer transactions.
Note: In previous versions of the Series 3000 software, the discrete batch application was not
approved for OIML compliance. The custody transfer (OIML) configuration is equivalent to the
configuration previously known as custody transfer (Europe). The custody transfer (OIML/batch)
configuration is new with transmitter software rev7.0.
