Near Intersection of I-35 & I-90 Southern Mn. | The Raven butterfly valve (the 2123 as you call it) would be a good choice. They used to be available in both the 1" and 1 1/2" styles. The 1" style is likely adequate for your sprayer.
Be aware that Raven makes a very basic butterfly control valve for their 203 kits which are manual control such as you have been using. These do not have limit switches and do not work out very well with an automatic rate controller. Without limit switches, the butterfly valve can go "over center" and the control is reversed which messes up the Inc/Dec in automatic.
As far as a flow meter, Raven makes good flow meters but they have gotten very expensive of late. When my Raven flow meter wore out on my Hagie sprayer, I was advised to go with a Micro-Trak flow meter which was much cheaper and seems to work fine. The connector on the flow meter or the wiring harness might need to be changed since it is quite possible that they won't mate.
Flow meters come in various capacity sizes. Generally you would not want one much larger than you need. An overly large flow meter is costly and may stall out at low flow rates. An overly small flow meter could restrict the flow and limit your ground speed. You can use your target rate, ground speed and sprayer width to compute the flow rate per minute for your various situations. This should help you decide on an appropriate flow meter capacity. There is a far amount of overlap so usually one size of flow meter would work for all your situations.
Some high capacity sprayers have two flow meters. They use one for certain jobs and both for the high capacity situations. EZ-Boom does not have the capability of using two flow meters at the same time. I would guess that you would not be in that situation anyway.
As far as your section ON/OFF valves, you should be able to continue to use your present electric ball valves.
Some styles of ball valves have internal relays and limit switches. They are wired with a constant 12V wire, a ground wire and a trigger wire controlled by a simple switch. If your switch box just uses a simple switch you have this type and you will be fine.
Some styles of ball valve do not have internal relays to reverse the motor rotation. They require using a switch or relay that switches the polarity between two of the wires. If your ball valves are this style you will need a polarity reversing relay box between the EZ-Boom and each valve.
Reply back if you have this style. Commercial Polarity reversing boxes are available or you can make your own.
