Boom Heights at Fan Angles Worksheet

Use this spreadsheet to calculate the minimum boom heights needed for various applications. Some caution: The values are theoretical and assume the fan angles are accurate. Some nozzles don’t produce the advertised fan angle. Enter your actual angle in the spreadsheet The theory assumes that the droplets at the edge of the fan always move […]

Diagnosing Airblast Coverage

Assuming there are no mechanical or maintenance problems, water-sensitive paper can be used to diagnose sprayer performance. Go here to read more about water-sensitive paper. Interpreting the results and knowing what changes to make is the critical part of the process. Observing no coverage, or a sodden paper, make for obvious conclusions… but what about everything in between? Here […]

The operator hopes to provide suitable coverage on both the sprayer-facing half of the canopy, and that half of the canopy facing the next alley. […]
