The differential pressure reading on the flow meter should be +/- 4% full scale of the
compared reading of the manometer
a.
Example: a full scale reading of 12”wcg should be +/- 0.48”wcg
4.
If the sensors are determined to be out of tolerance, the sensors may need to be
replaced. Please contact SSI for next steps.
Appendix 3: Startup Procedures
For optimal accuracy and control, the following procedure is recommended:
LED model:
1.
Zero Tare (Resets the zero flow rate of the meter)
a.
With the meter in manual mode, drive the valve completely closed.
b.
Enter the setup menu and enter
P6.10
c.
Change the value to 1 and press Select to save.
2.
Max Tare (Sets the max position the valve can drive to in valve position mode)
a.
With the meter in manual mode, drive the valve open to the desired max flow
rate.
b.
Enter the setup menu and enter
P6.50
c.
Change the value to 1 and press Select to save.
3.
Altitude Compensation
a.
Enter the setup menu and enter
P6.60
b.
Enter the actual altitude for the installed location.
c.
Press Select to save.
Touchscreen model:
1.
Zero Tare (Resets the zero flow rate of the meter)
a.
With the meter in manual mode and supply gas/liquid pressure applied to the
meter, drive the valve completely closed.
b.
From the main screen, enter the setup menu
and push the zero tare
button.
c.
This will zero the meter and the flow should adjust to zero accordingly.
2.
Max Tare (Sets the max position the valve can drive to in valve position mode)
a.
With the meter in manual mode and supply gas/liquid pressure applied to the
meter, drive the valve open to the desired max flow rate.
b.
From the main screen, enter the setup menu
and push the max tare
button
.
c.
This will set the current position of the valve to be the maximum position allowed
during normal operation.
3.
Altitude Compensation
a.
From the main screen, enter the Setup menu
and Instrument Configuration -
Additional Options menu
.
b.
Enter the actual altitude for the installed location.
c.
Press Select to save.
