Setting Advanced
Parameters
In the
ADVAN
option, you can enter parameters for two specialized
operations: static density and multiple K factors. While following the
programming instructions, refer to Figure A-2 on page A-2
.
To enter
the
ADVAN
submenu, press
[F4]
at the
SETUP
window.
Static Density
Use this option to specify basic parameters for mass flow
measurement.
1.
To enter the
MASS
submenu, press
[F1]
at the
ADVAN
window.
2.
At the
Static Density?
prompt, press
[F1]
=
NO
or
[F2]
=
YES
. If you
press
NO
, the GS868 returns to the
ADVAN
window.
3.
Enter the
Fluid Density
of the gas to be measured and press
[ENT]
.
(The meter will only accept values from 0.00001-100 lb/ft
3
.)
The GS868 program returns to the
ADVAN
window.
Entering Multiple K Factors
In the
MULTK
option, you can enter velocity or Reynolds Correction
values into a K-Factor table. You can thus “curve fit” velocity or
Reynolds calibration multiple data points (from several different data
sources or flow variables) to the flow rate reported by the GS868.
1.
Press
[F2]
to enter the
Multiple K Factors
option.
2.
Press
[F1] = NO
to disable or
[F2] = YES
to enable
Multiple K-
factors
.
•
If you press
NO
, the GS868 returns to the
ADVAN
window.
3.
If you press
YES
, the program asks for the
Custom type
of data.
Press
[F1]
to select velocity data, or
[F2]
to select Reynolds data.
a.
If you select a Reynolds table, the meter asks for the
Kinematic
Viscosity.
Enter the appropriate value, and press
[ENT]
.
4.
Press
[F1] = NO
to retain the current K-factor table and return to the
ADVAN
window, or press
[F2] = YES
to
Edit The K-factor Table.
Note:
If velocity vs. K-factor data was not provided with the Model
GS868, the K-factor table can not be edited.
a.
Enter the
Number of K-factors
to be entered into the table.
Press
[ENT]
. (The meter will only accept values from 2 to 20.)
IMPORTANT:
When editing the K-factor table, the velocities must
be entered in increasing order.
