2.3.3 Calculating the actual volume
The operating volume is calculated from the operating volumetric flow rate Q
v, cal
by
integration over time of the measuring intervals.
The total aggregated volume is stored in the operating volume counters for both directions
of flow. The operating volume counters can be reset if the Parameter write lock is
UNLOCKED.
While the system is in "Data invalid" status, the volumes determined are stored in separate
error volume counters. These counters can be reset. Such a reset is recorded in the
Custody logbook [1] together with date and time stamp.
The resolution of aggregated volumes per volume unit [m
3
or ft
3
] is defined in register
#5014 "TotalizerResolution". When reading the volume counters (#5010 to #5013), the
corresponding counter resolution must be considered.
