Pipe Wall
4.
Use the numeric keys to enter the known thickness of the
Pipe
Wall
. Press
[ENT]
.
If the pipe wall thickness is not available, look up the value in a table
of standard pipe size data or use the Model GS868’s on-line
Help
Menu
(see the
Programming Manual
for details).
Path Length
5.
Press
[F1]
= inch or
[F2] = feet
to select the units. Then, enter the
Path Length (P)
of the ultrasonic signal. Press
[ENT]
. (The meter
will only accept values from 1/8 to 900 in.)
Note:
The factory has calculated both the transducer signal path
length
(P)
and the transducer signal axial length
(L)
, based on
the exact transducer configuration used for the application.
These values are engraved on the flowcell and/or are included
in the documentation supplied with the meter.
Axial Length
6.
Press
[F1]
= inch or
[F2] = feet
to select the units.Then, enter the
Axial Length (L)
of the ultrasonic signal and press
[ENT]
.
Note:
The factory has calculated both the transducer signal path
length
(P)
and the transducer signal axial length
(L)
, based on
the exact transducer configuration used for the application.
These values are engraved on the flowcell and/or are included
in the documentation supplied with the meter.
Fluid Type
7.
Press
[F1]
= steam or
[F2]
= any other gas to select the
Fluid Type.
a.
If
OTHER
was selected, enter the speed of sound (in feet per
second) in the gas to be measured. Press
[ENT]
. (The meter will
only accept values from 125 to 9000 ft/sec.)
Reynolds Correction
8.
The
Reynolds Correction
factor is a number based on the
kinematic viscosity and flow rate of the gas. At the
prompt, press
[F1]
to turn Reynolds Correction off
,
or
[F2]
to turn it on
.
•
If you select Reynolds Correction, the GS868 asks for the
Kinematic Viscosity
of the gas (available in the brochure
Sound
Speeds and Pipe Size Data
, 914-004). Use the numeric keys to
enter the correct value and press
[ENT]
.
Calibration Factor
9.
Enter a value for the flow
Calibration Factor
and press
[ENT]
. The
default value is 1.00. (The meter will only accept values from
0.5000 to 2.0000.)
