Sprayer Turn Compensation

Turn compensation is a feature in pulse width modulation (PWM) sprayers in which nozzle output matches the boom’s speed during a turn. When turning, the inside and outside of a boom travel at different speeds, resulting in over-dosing on the inside and under-dosing on the outside. Read about PWM systems here, here, and here.

Diluting 20,000-Fold with a 30 Gallon Remaining Volume in a 1,200 Gallon Tank

(An addendum to this article) Our goal in this example is to dilute by a factor of 20,000. The maximum amount of dilution possible with a 1,200 gallon tank and a 30 gallon remainder is 1200/30=40. The formulae: Dilution per Rinse = final dilution ^(1/# of rinses) Rinse Volume = (dilution per rinse * remaining […]
