Quick Setup
Full Scale Flow Use Full Scale Flow to set the maximum flow the system is expected to measure. This parameter
influences other system parameters, including:
• 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 adjust the thresholds for generating set point alarms
• Pulse Outputs – Changes to Full Scale Flow adjust the pulse frequency and duty cycle
• Analog Outputs – Changes to Full Scale Flow adjust 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 suggested flow range limits. In terms of flow velocity, the meter
limits are 0.1…39.4 feet/second. The Full Scale Flow is valid for both flow directions.
OTE: N If the flow rate exceeds the full scale setting, an error message indicates the configured full
scale range has been exceeded. However, the meter continues to measure. This affects the
latency of the pulse outputs and may cause overflow. Furthermore, the analog output may be
placed in alarm mode.
To set or change the Full Scale Flow, follow these steps from the Quick Setup menu:
1. Select Full Scale Flow to view the Full Scale Flow display.
2. Select a value for Full Scale Flow.
3. Press [E] to save the Full Scale Flow value and return to the Measurements menu.
Low Flow Cutoff Low Flow Cutoff defines the threshold at which flow measurement is forced to zero. The cutoff value
can be set at 0…10% of the Full Scale Flow. Increasing this threshold helps prevent false readings
during “no flow” conditions possibly caused by pipe vibration or inherent system noise.
To change Low Flow Cutoff, follow these steps from the Low Flow Cutoff display.
1. Select a value for Low Flow Cutoff, between 0% and 10%.
2. Press [E] to save the value.
