Entering Multiple K Factors
- MULTK
Programming Site Data
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. Complete the
following steps to enter multiple K factors for velocity or reynolds
values:
Note: The factors are supplied by GE Infrastructure Sensing.
Without them the K-factor table cannot be edited.
1. Press [ESC], [ENTER], [ESC]. The meter enters the user program.
2. Press [ ] until PROG appears and press [ENTER].
3. Press [ ] until the desired channel appears. Press [ENTER] at CH1

10.Enter the number of K factors (2 to 20) in the table by using the
arrow keys. Press [

location and press
number and press [ENTER].
11.Enter the velocity/reynolds value for K-factor number "X" by
using the arrow keys. Press [
desired location and press
the number and press [ENTER].
IMPORTANT:
When editing the K-factor table, the velocities must
be entered in ascending order.
12.Enter the K-factor corresponding to velocity/reynolds number "X"
(0.333 to 3.0) by using the arrow keys. Press [
the cursor to desired location and press
or decrease the number and press [ENTER].
