Maximum Forward Flow Alarm Threshold
[Max + = Gal/m OFF]
Maximum Reverse Flow Alarm Threshold
[Max - = Gal/m OFF]
Minimum Forward Flow Alarm Threshold
[Min + = Gal/m OFF]
Minimum Reverse Flow Alarm Threshold
[Min - = Gal/m OFF]
Hysteresis Threshold
[Hysteresis = % XX]
Current Output Alarm State Value
[mA v.alarm = % XXX]
Frequency Output Alarm State Value
[Hz v.alarm = % XXX]
This function sets the alarm threshold for maximum forward flow. Flow rates
above this threshold will trigger the alarm. The threshold value is entered as a
flow rate in the engineering units shown. The minimum value must be ≥1% of
the full scale maximum flow rate of the meter (10m/s or 32.8ft/s velocity). Alarm
threshold values are entered in 1% increments of the full scale limit up to 100%.
Example: In a 6” pipe 32.8 ft/s is equal to 2853 GPM. 1% of this value would be
approximately 28.5GPM. Alarm threshold values would be entered in increments
of 28.5 GPM.
To enter a value, press enter to access the function. Use the up arrow and right
arrow keys change the threshold value. Press enter to accept the change and exit
the function. Press escape to exit the program mode.
This function sets the alarm threshold for maximum reverse flow. Flow rates
