Oh, and to answer your question I am not using all channels, but I'd like to keep it to one per meter since there are going to be multiple meters.
So the counter setting gives me a total pulses counting up from zero. I need to multiply that by the k-factor (pulses per gallon) to get true gallons. The problem I run into is that once a year we have k-factor changed when we do third party calibrations of our flow meters. So, if that k-factor changes, the whole count will change, not just the portion of the count from the point we changed the k-factor. I was going to just do a get and clear and add it to a variable over time, but then if I clear it the way I'm running my chart it will most likely mess up the GPM reading. So, I'm trying to figure out how to do both calculations in the same chart.
The other question I have is that a chart is run every 100mSec right? and do you have to have a delay added to that...I know it's recommended in most charts, but then if I'm calculating GPM based off of how many pulses in a second, does that then mean that the chart delay of 100mSec will mess up my second count, then adding 100mSec + delay to my real second interval?
basic problem is I'm trying to do this as accurately as possible to maintain a true reading.
