While there were a few large operations, most were small acreage hobbyists and part-time hops growers that did not have any experience spraying the crop.

Measuring Pressure Drop

All sprayers experience a drop in pressure as the solution moves further away from the pump.  Here’s why that’s important, and how to measure it. Optimal nozzle operation in terms of spray quality and fan angle is closely tied to spray pressure.  As we try to maximize travel speed range with a modern sprayer, we […]

Rate Controllers and Spray Pressure

Monitors

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 […]
