vApply HD
Variability with speed
This map, with the rate being measured with FlowSense, shows a definite change in rate on the east portion of the field. When placed beside the speed map of the same field, it is easy to see that the control system on this planter was sensitive to speed, applying 37 gpa at 3.5 mph and 30 gpa at 5 mph
Row-to-row variability
This map shows that this 24-row planter has 27% variability from the lowest to highest rate being applied, even when there was only one target rate across the entire field. Unexpected things, like whether the roll of hose was laid vertically or horizontally on the planter toolbar can affect the rate on that row, and may not even be seen.
Solving problems with simplicity
While FlowSense illuminated many of the problems above, we knew that only seeing an issue and not fixing it is frustrating. vApplyHD is that fix. Instead of many components to meter, swath, measure, balance, and divide, the vApplyHD system uses a pump control module and then control modules on the toolbar. The modules on the toolbar control flow, measure flow, and swath all in a single device. These same modules can be configured in either section control or row-by-row control. Whichever way you decide to go, the result is your liquid fertilizer is applied at the correct rate and the 20|20 display in the cab gives you knowledge of how that application is occuring.
Flow measurement, flow control, turn compensation, variable rate prescriptions. All of this done by the on-row vApplyHD module.
