Hello, I’m not sure if this has been asked before, but I just bought the Orbit Catch Cups to do the zone volume measurements. In the 1st zone I tested I surprisingly averaged 125 mL in 10 minutes out of 12 cups. The converts to 45.77 cubic inches/hr. Is this the number that I enter into the “Nozzle Inch Per Hour” box? That doesn’t make sense, it seems way too large. Are my units getting mixed up? Just seems the units for this box are a bit unclear.
Any suggestions or thoughts would be greatly appreciated. Thanks!
Try this website. You will need one catch cup area but perhaps Orbit has standardized them so the default might be OK (you’ll want to check!! Area is important in order to convert from 3D to 2D). You want inches/hr for the precipitation rate setting: http://irrigationaudit.hydrorain.com/get-started/#/audit
