I need to totalize a flow rate over a short time frame (25-80 minutes). The flow rate is in lb/s (I need total # of lbs over the duration) and I am using Event Frames to capture the event. There are data points for nearly every second over the duration as well. I'm trying to figure out which of the options is more accurate for this. I'm currently looking at doing this in AF so that historical data can still be tracked and Event Frames can be back filled.
TagMean(Tag, EventStart, EventEnd) * EventCount(Tag, EventStart, EventEnd) * EventFrame("Duration")
TagTot(Tag, EventStart, EventEnd) * EventFrame("Duration")
