The second step (Page 2 of 3) in the calibration process is the selection of the
engineering units with which the calibration will be performed. Select the Flow Rate
Units and click the Next button at the bottom of the window.

It is advisable to File Save the existing calibration before modifying it. If the Flow Rate Units selected on this page do not
match the Flow Rate Units utilized for the existing data points collected on Page 3 of 3, flow measurement errors can occur.
To view measurement units, go to Page 3 of 3 and press Edit. The Calibration Points Editor will show what units
were used during the existing calibration.
1) If no data exists in the editor, selection of Flow Rate Units will not influence measurements.
2) If new calibration points are to be entered on Page 3 of 3, it is advisable to remove the existing calibration
points using the Calibration Points Editor.

Figure 5.9 - Calibration Page 2 of 3
Page 3 of 3 as shown in Figure 5.10 allows multiple actual flow rates to be recorded.
To calibrate a point, establish a stable, known flow rate (verified by a real-time
primary flow instrument), enter the actual flow rate in the Figure 5.10 window, and
click the Set button. Repeat for as many points as desired.
Note: If only two points are to be used (zero and span), it is preferable to use the highest flow rate
anticipated in normal operation as the calibration point. If an erroneous data point is collected,
remove it pressing the Edit button, selecting the bad point, and then selecting Remove.

Zero values are not valid for linearization entries. Flow meter zero is entered on Page
1 of 3. The following error message appeard if a zero calibration point is attempted.

Target Dbg Data Screen - Definitions
1. Calc Count - The number of flow calculations performed since the meter was last
power cycled.
2. Sample Count - The number of samples taken per second.
3. Raw Delta T (ηs) - The duration of one ultrasonic pulse crossing the pipe.
4. Course Delta T - The meter uses 2 wave forms: a coarse wave to find the best delay
and other timing measurements, and a fine wave for the flow measurement.
5. Gain - The amount of signal amplification applied to the reflected ultrasound pulse
to make it readable by the digital signal processor.
6. Gain Setting/Waveform Power - The first number is the gain setting on the digital
pot (automatically controlled by the AGC circuit). Valid numbers are from 1 to 100.
The second number is the power factor of the current waveform. For example "8"
indicates a 1/8 power wave form.
Cancel
7. Tx Delay - The amount of time the transmitting transducer waits for the receiving
transducer to respond before the transmitter initiates another measurement
cycle.
8. Flow Filter - The current value of the adaptive filter.
9. SS (Min/Max) - The minimum and maximum signal strength levels encountered by
the meter beginning at the time the meter was power cycled.
10. Signal Strength State - Indicates whether the present signal strength minimum
and maximum are within a pre-programmed signal strength window.
11. Sound Speed - The actual sound speed measured by the transducers.
12. Reynolds - A number indicating how turbulent a fluid is. Reynolds numbers
between 0 and 2000 are considered laminar flow. Numbers between 2000 and
4000 are in transition between laminar and turbulent flows. Numbers greater
than 4000 indicate turbulent flow.
13. Reynolds Factor - The value applied to the flow calculation to correct for variations
in Reynolds numbers.
14. Serial Number - The serial number reported by firmware.
Saving Meter Configuration on a PC
Save the complete configuration of the flow meter from the Configuration screen.

name the file. Files are saved as a *.dcf extension. This file may be transferred to
other flow meters or may be recalled should the same pipe be surveyed again or
multiple meters programmed with the same information.
Printing a Flow Meter Configuration Report
Select File from the upper task bar and Print to calibration/configuration information
sheet for the installation.
