Totalizer Unit
When Flow output type is
Mass Flow, Totalizer Unit lists:
 Kg
 G
 ShTons
 LTons
 Mton
 Lb
 Ounce
 Custom Unit
When Flow Output type is
Volume Flow, Totalizer units
lists:
 M3
 Barrels
 Ft3
 Nm3
 nLiters
 Liters
 scft
 Scm
 Gallons
 Custom Unit
When Custom Unit is selected,
related parameters will be
enabled:
Custom Unit Tag
Base Unit
Base per Custom unit
Conversion factor
This is the user-configured engineering unit
for the Totalized Value. The user may
select any of the standard engineering units,
or custom units may be selected. For
custom units, the user must provide a units
tag name, a base unit, and a conversion
factor for converting from the base unit to
the custom unit.
(value in Custom unit =value in base unit *
conversion factor)
Totalizer Mode
This parameter indicates the current mode
of the Totalizer as RUN or STOP.
Start/Stop Totalizer
 Start Totalizer
 Stop Totalizer
This method will allow the user to Start the
Totalizer or Stop the Totalizer.
Max. Totalizer Value
This is a user configurable value indicating
the maximum Totalizer value. When the
Totalizer Value reaches this maximum
value, it automatically resets to zero and
continues totalizing. It also increments the
Exceed Counter.
On a Negative Totalizer Max value, with a
decreasing Total Flow value, Totalizer will
reset only on crossing the negative max
value.
Ex: Totalizer Max = -1000lb
On an emptying Tank, say Totalizer reaches
-100, -200, -300 etc. Even though -100, -
200 etc are greater than -1000, this does
not cause Totalizer Reset until after the
Totalizer goes below -1000. Here Exceed
counter will be incremented every time
Totalizer reaches below -1000 lb.
