For well under 3K you could install a spray
controller. I'm most familiar with Raven,
was a service tech for years. Also Dickey John
and Spray Systems, and a few others
are popular.
Install unit, set for desired gallons per acre,
and drive.

Nice stuff but too much $. I have three sprayers and three tractors. Any
unit can mount anyplace.

Are you trying to determine your traveling rate(mph), or the pump
speed driven by the PTO, or?

I just hold everything constant. 4rth gear, 1200 RPM, 32 PSI gives 44 gal
per acre on one sprayer. The air blast at the same settings gives 85 gal per
acre. I then put in 1/2 the acre label amount in that much water. That much
reduction don't work for herbicides
I have acreage marked off and double check that everything is running right.
The goal here is to make the 2000 run just like the 3600.

OK.
I have a Spray Systems monitor on our sprayer. Really the only thing
I use it for is an accurate speedometer. It has a magnetic pickup on
the axle. It's the really cheap model. It was about $200.
The rest is formulaic. X pressure, at X mix ratio will be so many
units/acre at X speed.
It would probably be pretty easy to move the unit between multiple
machines if one had the need. (I don't). Just add pickup on each
machine and just move the monitor. Or move the pickup and sensor
between them too. But the sensor is so cheap, that having one on each
wouldn't be much and would be a lot easier.
