The user may select any of
the standard engineering
units, or custom units. 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)

When the Totalizer is set to
Run mode after a Reset, it
will start incrementing /
decrementing from this base
value.

This is the Totalized Flow for
Reverse flow only. The
Negative Totalizer will
decrement when the Flow
Rate is a reverse flow
(negative flow value).
Note that the Reverse Flow
configuration setting must be
enabled to calculate negative
flow.

Totalizer value
755
This is the Totalized Flow for
Forward flow only. The
Positive Totalizer will
increment when the Flow
Rate is a forward flow
(positive flow value).
