I've measured the flow of these emitters. Would this be useful to you? I've measured Liter per Minute to the .25 Liter on various emitter qtantities, 1, 3, 6, 9, 12, 18, 24, and 36. I've also measured on various durations, 1, 3, 5, 10, and 30 mins.
Would this be useful to you? I have an .xls I can send.
Also, I want to state, that I am no longer interested in duration that is a fraction of a minute. A minute will be short enough for me.
