13.3.1
Overflow of the Flow Totalizers
The overflow behavior of the flow totalizers can be set:
Without overflow:
• The value of the totalizer increases to the internal limit of 10
38
.
• The values will be displayed as exponential numbers (±1.00000E10), if necessary. The flow totalizer can only be reset to
zero manually.
With overflow:
• The flow totalizer will be reset to zero automatically when ±9999999999 is reached.

.
Independently of the setting, the flow totalizers can be reset to zero manually.
Press key
to scroll through the upper line and display the totalizers.
The totalizer value will be displayed in the upper line (here: the volume which has passed
through the pipe at the measuring point in positive flow direction since the activation of the
totalizers).
This error message will be displayed if the totalizers of a measuring channel where the flow
velocity is measured are to be activated. The flow velocity cannot be totalized.
If
one
is selected, only the value of the totalizer that is currently displayed will be stored.
If
both
is selected, the values of the totalizers for both flow directions will be stored.
Press ENTER.
If
on
is selected, the values of the flow totalizers will be stored and used for the next mea-
surement.
If
off
is selected, the flow totalizers will be reset to zero.
Select
on
to work with overflow. Select
off
to work without overflow. Press ENTER.
Note!
The overflow of a totalizer influences all output channels, e.g., data logger, online transmission of
data.
The output of the sum of both totalizers (the throughput
Q
) via an output will not be valid after the
first overflow (
wrapping
) of one of the corresponding totalizers.
To signalize the overflow of a flow totalizer, an alarm output with the switching condition
QUANT.
and
the type
HOLD
has to be activated.
