(Max. Count Speed). Use 3kHz with turbine flowmeters.
Select the proper input termination.
Enter the desired Maximum Sample Window Time (1-99
sec) that can occur at the lowest flowrate. Use 1 second
for turbine flowmeters.
Enter the desired K-Factor Type.
If Avg selected, Enter the desired Average K-Factor in
the units requested.
If LinTbl selected,
Enter the desired frequency/ K-Factor pair for each point
in the Linearization Table.
NOTE: Enter 0 for Fre value of any point (other than
Fre01) to exit the routine and use the values
entered up to that point.
Enter the desired volumetric Low Rate Alarm.
This will trigger an alarm message if alarm conditions
occur. The relays are not affected.
Enter the desired volumetric High Rate Alarm.
This will trigger an alarm message if alarm conditions
occur. The relays are not affected.
