2.2.3 Totalizers Flow volume can be totalized separately for each connected
instrument. Each totalizer will roll over when an ensemble is
received, or when volumetric units of measure are changed.
The totalizer rolls over to zero when it reaches a certain value;
this value is determined by the units of measure for volume, as
shown below:
Note that an alarm to indicate when a rollover has occurred can
be set by using the rollover value as an alarm for Totalized Flow
(Refer to Alarms, on page 2-8).
