Gauge Calibration
For optimum performance, calibrate the gauge exactly as described below.
It is assumed that the gauge has been installed properly, the shutter is open
(if applicable), the pipe is empty of any fluid, and that the SGD-O
transmitter is being used.
A condensed version of this procedure can be found in Appendix D . The
appendix also provides space to record values.
Note
Reference Chapter 2 for instructions on how to use a direct access
code (DAC).

1. Erase memory (DAC 74 ). This step is necessary to ensure that all data
is reset to factory defaults.
2. Load the standard oilfield setup into transmitter memory (DAC 1016 ).
After loading the setup, the top line of the display will be Measurement
1, which is lbs/Usg SolAdd. {This unit is equal to today’s PPA (pounds
of proppant added) per US gallon of carrier fluid. The measurement
may have also been in PSA (pounds of sand added), which is pounds of
proppant added per gallon of carrier fluid pumped.}
The second line of the display will show the bulk density in lb/US Gal,
and the third line will show the bulk density in g/ml.
3. Enter the pipe ID in inches (DAC 048003 ). It is important this value
be as accurate as possible.
Caution
Once the pipe ID is entered, do not change it, even if the entry is
incorrect. Changing the value after calibration is performed will invalidate
the calibration.
