5. Enter the passcode in the following sequence to adjust the
reading:
a. HAND/AUTO
b. CIP
c. ALARM BYPASS
6. While machine is running, compare the concentrate flow rate
on the ECM-100 to the bucket test concentrate flow rate
measured in Step 8 of Calculating Concentrate Flow Rate
(Section 8.7.2).
7. If the flow rates differ by more than 0.3 gpm (0.07 m
3
/H) the
“Conc Flow Rate Slope” needs to be adjusted (increased or
decreased to reflect the actual flow rate of the bucket test).
8. If the flow rate displayed on the ECM-100 is less than the
bucket test the Concentrate Flow Rate Slope setting must be
increased. If the flow rate displayed on the ECM-100 is more
than the bucket test the “Conc Flow Rate Slope” must be
decreased.
• Press the ARROW keys to increase or decrease the slope
by increments of 2 and compare the Concentrate Flow Rate
to the bucket flow rate.
• Press ENTER to save the value.
NOTE:
In order for the ECM-100 to acknowledge the new slope value wait 20
seconds after ENTER is pressed for a new reading.
9. Observe “Conc Flow Rate.” If additional adjustment is
necessary, repeat Step 8.
It may be necessary to repeat this process several times in order to
properly calibrate the concentrate flow rate.
If the flow reading is always low, even with a slope value of 46,
refer to ECM-100 Troubleshooting (Section 7.2).
NOTE:
Actual flows tend to fluctuate somewhat normally, so extreme accuracy is
often not possible.
