1.8.4 Using Advanced Features
This option enables you to access the more advanced features of the meter. In this option you can do the following:
•
enter a table of K factors
- to compensate for non-linear flow rates (see below).
•
enable mass flow
- calculated for static fluid density (see the next page).
1.8.4a Entering K Factors
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)
that compensates for non-linear flow rates. The meter accepts from 2 to 20 data pairs. Complete the following steps to
enter multiple K factors for velocity values:
Note:
The K factors are supplied by the factory; without them the K factor table cannot be edited.
1.
In the
Keypad Program
, scroll to
PROG
and press
[Enter]
.
2.
In the
PROG
menu, scroll to
CH1
or
CH2
and press
[Enter]
.
3.
In the
Channel PROGRAM
menu, scroll to
Setup
and press
[Enter]
.
4.
Scroll to
ADVAN
. Press
[Enter].
5.
Scroll to
MULTK,
and press
[Enter]
.
6.
Scroll to
ON
to activate, or to
OFF
to deactivate multiple K factors, and press
[Enter]
.
Note:
If you selected OFF, go to
Procedure Options
on the next page.
7.
Scroll to the
Custom Type
of K factor desired: CstV (velocity) or CstR (Reynolds). Press
[Enter].
•
If you selected CstR, the meter asks for the
Kinematic Viscosity.
Use the arrow keys to enter the desired value,
and press
[Enter].
8.
Scroll to
Yes
to
Edit Table,
or to
No
to retain the current values
,
and press
[Enter]
.
Note:
If you scroll to No, go to
Procedure Options
on the next page.
1.8.4b Editing K Factors
1.
Use the arrow keys to enter the number of K factors (2 to 20) in the table and press
[Enter]
.
2.
Enter the velocity (or Reynolds) value for K factor number “X” and press
[Enter]
.
Note:
When editing the K factor table, the velocities must be entered in increasing order.
3.
Enter the K factor corresponding to velocity number “X” (0.333 to 3.0) and press
[Enter]
.
4.
Repeat Steps 2 and 3 for each pair of values.
