Selection of the flow totalizers for storing
It is possible to only store the value of the flow totalizer that is currently displayed or one value for each flow direction. Se-
lect Special Funct.\SYSTEM settings\Storing\Quantity Storage.
When the measurement is stopped
The behavior of the totalizers when the measurement is stopped or after a reset of the transmitter is set in Special
Funct.\SYSTEM settings\Measuring\Quantity recall.
12.2.1 Overflow of the flow totalizers
The overflow behavior of the 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.
Select Special Funct.\SYSTEM settings\Measuring\Quant. wrapping.
Independent of the setting, the flow totalizers can be reset to zero manually.
12.3 Settings of the NoiseTrek parallel beam mode
The NoiseTrek parallel beam mode works using parallel mounted transducers. It improves the signal quality when mea-
suring on small pipes or with strongly attenuating fluids.
If one is selected, only the value of the totalizer currently displayed will be stored. This can
apply for the positive and negative totalizer.
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., the data logger and the online trans-
mission of data.
The output sum of both totalizers (throughput Q) transmitted via an output is not valid after the over-
flow (wrapping) of one of the 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.
Select Special Funct.\SYSTEM settings\Measuring. Press ENTER until the list
item Enable NoiseTrek is displayed. Select on to enable the NoiseTrek mode, off to
disable it. Press ENTER.
Select on to enable the NoiseTrek parallel beam mode, off to disable it. Press ENTER.
This display will only be indicated if the NoiseTrek mode is enabled.
