Output pulse lenght
(for models ILR750 and ILR750T)
Indicated by a “P” on the left hand side of the display, this screen allows the selection of the low duration of the output pulse.
•
“0” for zero milliseconds (pulse output is disabled)
•
“2” for 2 milliseconds
•
“10” for 10 milliseconds
•
“20” for 20 milliseconds
•
“40” for 40 milliseconds
•
“100” for 100 milliseconds

Output pulse lenght screen
About Output Pulse Length : The pulse rate duration should take into account the "Pulse Rate Out" and maximum meter
flow rate, to prevent an output pulse duration greater than the required time between pulses. The
Output Pulse Length
should be set to less than the value of “t.”
Per the equation:
Maximum meter flow rate (in GPM or l/m)
t = ----------------------------------------------------------------- x 1000
60X output pulse rate
where t = the required pulse rate in milliseconds.
The output pulse rate = the programmed parameter (default = 1.00 PPL/PPG)
The maximum meter flow rate = the maximum flow rate of the meter for the application.
