ARAG FlowTRON and Carbon BEE Integration: Revolutionising Spot Spraying

In a groundbreaking collaboration, ARAG and Carbon BEE have unveiled the ARAG FlowTRON / Carbon BEE integration, addressing the persistent challenges of spot spraying with unparalleled precision and efficiency. This innovative solution promises to transform agricultural spraying practices, particularly for broad-acre farmers in Australia. Here's how this cutting-edge technology solves spot-spraying problems and delivers exceptional results.

Comparing nozzle angles and spray widths for Carbon BEE system configuration - Part 10a.

This is just to follow on with the discussion relating to nozzle spray widths. Let's compare the spray widths of 110°, 80° and 60° nozzles.

CASE Dealers installing CARBON BEE, please listen up about the danger of using standard 110° nozzles with incorrect settings - Part 10.

The first thing to understand about how the CBEE determines which nozzles to activate is this. The CBEE will turn on nozzles where a weed appears in the footprint (spray width) of the nozzle as specified in the configuration settings.

Providing WHAT IS MISSING from JD's See & Spray Nozzle Pocket Guide? - Part 8.

Understanding the relationship between isolated and overlapping nozzles is vital for correct nozzle selection. Unless you get that right and are clear on what your target objectives are, chemical batching and post job reporting will be suspect as well.

What's missing from JD's See & Spray Nozzle Pocket Guide? - Part 7.

The See & Spray Nozzle Pocket Guide provides all the information to work out a per nozzle flow rate required based on band width for single spot (isolated nozzle) applications. There are two sets of tables that provide theoretical values which should be used in place of nozzle spacing in the final worksheet.

Raising the curtain on the spraying part of spot spraying...figuring out controller rates - Part 6.

It has been quite a journey and I have ruffled a few feathers along the way in my quest to bring some accuracy and precision to the complex art of setting up a sprayer for isolated nozzle operation, that is to say Single-Spot Spraying.

The problem with Camera / Spot sprayers that nobody wants to talk about - Part 5.

Since all spot sprayers are not the same, I'm going to classify them into three main groups. I'm not concerned with cameras or sensors just the rate controller and nozzles. The spraying bits.

The problem with Camera / Spot sprayers that nobody wants to talk about - Part 4.

Based on my assessment and absent any evidence to the contrary (after publishing this information widely), it appears that EVERY single spot capable camera system, at least in Australia has a rate controller calibrating on blanket, not spot rates.

The problem with Camera / Spot sprayers that nobody wants to talk about - Part 3.

In the last two episodes we’ve discussed the problems associated with switching from side safety to single spot, that is halving of the rate (approximately) and understanding that where multiple nozzles engage in single spot mode the rate between them doubles (approximately)

The problem with Camera / Spot sprayers that nobody wants to talk about - Part 2.

Last week I wrote to you about what happens when you switch your spot spraying system from side safety (multiple nozzles) to single spot, that your application rate for isolated nozzles could drop off by up to half or even more depending on nozzle height, size and angle.

The problem with Camera / Spot sprayers that nobody wants to talk about - Part 1.

When you take a spot spraying system and attach it to a boom sprayer, the expectation is that it will just work like normal. Well if two or more adjacent nozzles are firing, it probably does.
