@rraisley – Repeating my reply, this time using “@”…
Thanks for the quick reply. I bought a couple of boxes of catch cups a couple years ago and haven’t used them yet. I need to draw a decent map of the yard and put the cups out – hopefully in the next couple weeks.
Real Nozzle Inches per Hour is tough because I’ve got some rotors going 360 degrees, some going 180, some doing 90 degrees. I have different size nozzles in each rotor depending on the sweep and water requirements of that part of the yard (the shaded areas need less water, the bright sun areas need more). I figure I’ll use the catch cups to collect a number of data points per zone to get an overall estimate of inches per hour over the entire zone, then divide by the number of nozzles (rotors) to get an average inches per hour per nozzle rate.
