Output pulse length
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
To advance to the next programming screen, hold the TOTAL button.
Output pulse length 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
60 X 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.
