There’s been a lot of talk about rate control in spraying, and one key technology is pulse-width modulated spray systems (PWM). Although PWM has been commercially available for a number of years, we are seeing new products enter the market. This article explains what PWM is and how to make it work in a spray […]

There are many advantages to using rate controllers, but their primary role is to maintain a constant application rate. All sprayers change speed on hills, at row-ends, or in response to surface conditions. Since flow from an uncontrolled sprayer is constant, the application rate varies significantly (up to 40% in hilly conditions). Rate controllers compensate […]
This is the first of a series of short, educational and irreverent videos made with Real Agriculture to bring a little levity to sprayer education. Let’s face it – ironically, nozzles can be pretty dry. This first video discusses what a rate controller can be expected to do, and what it cannot do. Plus, we […]

Automatic rate controllers are standard equipment on almost all new sprayers. They ensure consistent application volumes, but they don’t do all the thinking for you. We explore how to make them work properly. A rate controller needs to know the boom width (entered by the user), the total spray liquid flow rate (from a flow […]
