Gauge Calibration Records
Following is a condensed version of the procedure detailed in Chapter 4 . It
is assumed that the gauge has been installed properly, the shutter is open (if
applicable), and the pipe is empty of any fluid.
Date Gauge Pipe Size (inches) Pipe ID (inches)
Step Description Command DAC Location or DAC Value
1 Erase memory. 74
2 Load standard oilfield setup. 1016
3 Enter pipe ID (inches). 048003
4 Standardize the gauge on air. When complete, fill pipe with
clean water. Allow detector to stabilize for five minutes. 121
5 Calibrate on water. 4
6 Record the water/air ratio. 118003
7 Use pipe size and water/air ratio to obtain the factor from the
tables (
Appendix C ). Record the factor.

8 Clear “Cal Point Pending” message. 49
9 Reset CAL/REF ratio to 1.00. 086003
10 Standardize the gauge on water. 121
11 Record the water signal value. 128003
12 Calculate the ZnCl signal value: ZnCl = Water signal * Factor.
13 Enter the calculated ZnCl signal value. 133003
14 Hold the output at ZnCl signal value. 137
15 Displayed density should be near 1.812 g/ml. (Record value.)
16 Record the slope correction factor. 049003
17 Record the carrier specific gravity. 085003
18 Displayed density should be 1.812 g/ml. Adjust slope
correction factor if necessary until density is 1.812 g/ml. 049003
19 Clear all holds. 9
20 Displayed density should be 1.000 g/ml. (Record value.)
