The frequency measurement mode can also be configured for a volumetric flow
measurement type in which case the data ranges screen will have different
configuration options as shown below.
Standalone Operation
3
1. Engineering Units
Allows selection of various flow measurement units.
2. K Factor
Enter the K factor provided on by the flow meter manufacturer.
3. Display Range
This is the linear mapping of the input range in terms of engineering units.
This determines what will be shown in the data display area for a given
input value.
4. Zero Adjust
This allows for a single offset value to be entered which will be applied to all
readings in terms of the selected engineering units.
5. Graph Range
This is a subset of the display range. This determines what portion of the full
display range will be displayed initially in the waveform views. This range
can also be adjusted from the waveform view.
6. Decimal Places
Select the number of decimal places for display here.
Example: Frequency=250 Hz.
Flow Rate Engineering Unit=GPM
K Factor=135.6 Pulse/Gallon
Flow Rate=(Frequency / K) *60=110.6 GPM
