Totalizer Unit
[USG]
U
This parameter establishes the units of measure for the totalizers.
To change the Totalizer Unit value, follow these steps from the
Measurements menu
:
1. Select
Totalizer Unit
to view the Totalizer Unit display.
2. Position the arrow next to one of the following totalizer units:

Full Scale Flow
[Factory Set]
U
This parameter sets the maximum flow the system is expected to measure. This parameter has influence
on other system parameters. These parameters include:
• Frequency Output – Full scale frequency is observed at full scale flow
• Low Flow Cutoff – Changes to full scale flow affect the measuring cut-off threshold of the meter
• Alarm Outputs – Changes to full scale flow adjusts the thresholds for generating set point alarms
• Pulse Outputs – Changes to full scale flow adjusts the pulse frequency and duty cycle
• Analog Outputs – Changes to full scale flow adjusts the interpretation of the analog output signal
Change the full scale flow based on the meter size and the application’s requirements. Verify that the
full scale flow falls within the meter’s suggested flow range limits. In terms of flow velocity, the meter's
limits are from 0.1 to 39.4 feet/second.
The full scale flow is valid for both flow directions.
Note: If the flow rate exceeds the full scale setting, an error message indicates that the
configured full scale range has been exceeded. However, the meter will continue to measure.
This will affect the latency of the pulse outputs and possibly cause overflow. Furthermore, the
analog output may also be placed in alarm mode.
To change the Full Scale Flow, follow these steps from the
Measurements menu
:
1. Select
Full Scale Flow
to view the Full Scale Flow display.
2. Set the full scale flow value to the desired setting.
3. Press
[E]
to save the full scale flow value and return to the Measurements menu.
