Calculating Kinematic
Viscosity
Use the KVTab option to calculate the kinematic viscosity (KV)
based on signal strength (SS) or temperature. To use this option, you
must select either a static KV value (entered at the Kinematic
Viscosity prompt in the PIPE submenu), a table of KV/SS values
(entered in the KV/SS submenu, discussed on page 1-60), or a table
of temperature vs. viscosity values (entered in the TmpKV submenu,
discussed on page 1-61).
1.
At the
ADVAN
window, press
[F1] =KVTab
to select
KV Input
Selection.
2.
Press
[F1]
to use a static KV value,
[F2]
to activate the table of KV/
SS values, or
[F3]
to activate a temperature vs. viscosity table.
a.
If you select Tmp/KV, the program asks for the specific
Fluid
Table
. Press
[F1]-[F3]
to select the desired table.
The DF868 returns to the
Advanced Features
prompt.
Entering a K-factor Table
Use this option to enter a table of K-factors. K-factors are used to
create a curve for the flow range (based on velocity or Reynolds
number) that compensates for non-linear flow rates. The DF868
accepts from 2 to 20 pairs. Complete the following steps to enter
multiple K-factors:
1.
At the
ADVAN
window, press
[F2]=MultK
to select
Multi K Factors.
2.
Press
[F1]
to disable this option, or
[F2]
to
Activate Multiple K
Factors
. If you select
NO
, the DF868 returns to the
Advanced
Features
prompt.
3.
At the Custom Type prompt, press
[F1]
to customize velocity
values, or
[F2]
to customize Reynolds values.
4.
Press
[F1]
to retain the current K-factor table, or
[F2]
to
Edit the K
Factor Table
. If you select NO, the DF868 returns to the
Advanced
Features
prompt.
Note:
If the necessary velocity/Reynolds vs. K-factor data was not
provided with the DF868 documentation, the K-factor table
cannot be edited.
5.
Enter the
Number of K-factors
to be entered into the table (from 2
to 20) and press
[ENT].
IMPORTANT:
When editing the K-factor table, the velocities
must
be entered in increasing order.
6.
Enter the
Velocity (or Reynolds) Value
for K-factor number 1 and
press
[ENT].
7.
Enter the
K-factor
corresponding to the velocity or Reynolds
number 1 and press
[ENT].
The
VELOCITY#
(or
REYNOLDS #
) and
K FACTOR
prompts repeat for each
pair. After you have entered all the pairs, the meter returns to the
Advanced Features
prompt.
