| Good stuff. I can't help specifically for the ball for the Visagauge system, as the balls are different weights than Wilgers, but you can use our Tip Wizard flow indicator calculator to easily calculate the flow rate per flow column.
https://www.wilger.net/tip-wizard-frame_v3/#/flowindicator
For the columns with the 2 per column, once you get the jist of where your balls are when you are spraying normally, you might be in a good spot to put a line on the column, as they will only tell you the relative flow if you had it next to the other 2 per outlet columns.
So, in the Tip Wizard tool, you'd just plug in:
Application Unit: US GALLONS/ACRE
Application Rate (this is PER nozzle) :
Average Travel Speed:
Nozzle Spacing: 20" (for now at least)
Weight of Liquid: If you are spraying only chemical/water, then probably just use 8.34 lbs/Gallon
Number of Outlets per flow column: For the columns that are monitoring 3 outlets, put in '3', and then check the flow rate calculated in the results area. Then swap the number of outlets to '2', and check the flow rate. The '2' columns should be 2/3 of the flow rate calculated for the 3-outlet columns.
For example, if you were putting down 10 US GPA, on 20" spacing, at 10MPH, and 2-outlets per column, your flow rate would be 0.673 us gallons/minute per outlet. So you'd follow the Visagauge chart and see what is the best ball.
For the 3-outlet example, with the same application rate/info, but 3-outlets per column, it'd be 1.010 us gallons/minute per column.
Again, you can ignore the column size and ball colors in the chart. that'd just be for the Wilger flow indicators. Visagauge will have its own.
