29.2 Day Totals
The table below shows the flow rate totals taken in the last 24 hours.
Fig. 29-4
Selection Day Totals
Up to 100 totals (= 100 days) are saved. Starting with the 101
st
value the oldest value will be
overwritten (ring memory).
A
prerequisite
to indicate older values is that the instrument has been running for a longer
period.
Example: 98 values – the unit has completed 98 totalising processes, so it must be running for
at least 98 days.
In general, only day totals can be viewed which have been created while the instrument was
actually in operation.
As soon as the NivuFlow Mobile is shut down between two totalising events (< 24 hours) the
transmitter creates a total using
measured
values. Such totals are
not equal to the actual
day total
but reflect the total measured by the transmitter while being in operation.
As soon as the transmitter is shut down before the next totalising event and remains to be off
until the next totalising (> 24 hours) no totals will be created for this period (Fig. 29-5 pos. 2).
No data will be stored and no name will be created for this period. This "gap" can be identified
from the completely missing entry (date/values) within the listed sequence.
No empty lines
will be created.
