Aim command pro actual volume vs rate controller volume count

I can understand that AIM command pro actual acres will differ from the rate controller acres because it's doing every nozzle instead of full sections. But why would it count volume differently? I noticed just now that the actual volume aim command pro reported was about 1800 gallons, but the other number was around 2000.

I have a pinpoint system on Deere sprayers, not sure if this will relate or not. My Deere system doesn’t know that some nozzles are being shut off, it only knows when whole sections shut off. So, when Deere says tank empty, there is some left due to this. Basically this shows you what the tip by tip sectional has saved you. But can be a pain when trying to mix just the right amount.

That does not make a lot of sense, volume should be counted by the flow meter which is before the booms or nozzles. Flow meter does not care what the nozzles are doing.

The volumes do read different. I believe the pinpoint manipulates the flow meter calibration because the rate controller thinks a full section is on but really it might not all be on.

Hmm. That is really weird though, like sasksodbuster said. I could understand if it was some kind of theoretical savings number, such as the gallons saved because you didn't overlap at all on a section.

Basically I'm trying to calibrate my AccuVolume sensor so I'm wondering which number to trust!

The aim command pro number would be the right one

Call me if you have questions when you start to calibrate.

So there are four different gallon counters that I can find between the AFS 700 and the Aim Command Pro monitor. And they all differ, even if I'm just doing a stationary test with all nozzles on. My gut feeling is that the "actual" number from the Aim Command Pro monitor is the one I want to use to calibrate from. The others vary by a fair amount (a few percent at least). Kind of odd. still don't understand why they all count differently.

Guess it helps to read the manual. The correct and most accurate volume number will be the "actual volume" in Aim Command Pro. Essentially Aim Command Pro takes the actual flow meter pulses value and adjusts it to drive the Case rate controller. As nozzles turn on and off it may have to adjust things on the rate controller side, and it does this by fudging the flow sensor readings.


Also learned today that it's important to make sure I'm on the right nozzle setting preset in Aim Command Pro or the rates will be way off!
