My EKM 3/4" water meter has the two pulse-output wires and it is giving accurate pulses wired to my Omicron H7EC counter. Rather than installing a $200 Hunter Flow-Sync wired to my Hunter I-Core commercial irrigation controller, I'd like to use the pulse output directly from the EKM water meter.
There is a "K-Factor" and an "Offset" setting that is needed to configure a non-Hunter flow sensor. The Hunter manual states this is specified by the manufacturer of the flow sensor. As I understand it, the K-Factor is defined as the number of pulses generated per unit of volume. The EKM 3/4 " meter specifies 1 pulse = 0.1 cubic feet or 0.75 gal. That would be the K-Factor. However, I'm not sure what the Offset would mean, other than the accuracy rate or min/max flow rate. Any clues on what this would mean, of if it is even important at all.

Re: Reading pulse signals to external controller
Hello,
Im sorry, but I am not sure what they are wanting in terms of "Offset", I have never heard this term before in regards to pulse outputs or pulse counting.
I wish I could be of more help here. Let us know if you find out what it means!
