Corner-arm and Z-corner programmable control

A common problem with corner-arm and z-corners is that even though they sequence sets of valves to try and keep irrigation application as even as possible, there are still downfalls due to either the irrigator not cycling valves in the correct positions, or ground conditions that require more or less water than the corner-arm system applies.

The Precision Irigation Corner-arm or Z-corner control system is a cut down version of the full VRI system which only controls valves on the corner or Z sections of the irrigator. Every sprinkler is controlled individually to give maximum control. The amount of water applied under every part of the corner / z is fully programmable and updatable.

If you wish to upgrade to full VRI over the entire machine, you only need to add the valves, nodes and wire loom, as the controller can be reprogrammed to control VRI over the entire machine.

Corner-arm and Z-corner programmable control

The Precision Irrigation Corner-arm and Z-corner sprinkler control system is essentially a cut-down full machine Variable Rate Irrigation system, programmed to control valves on only the corner-arm or Z-corner spans of a center-pivot irrigator.

The application rate is programmed as a percentage of the rate being applied by the rest of the machine and valves will be individually pulsed to control the depth of irrigation applied beneath the corner arm.

If too much or not enough water is being applied on any part of the field by the corner arm, you simply re-program that part of the field to receive less or more water from the corner arm system which will reconfigure how the individual valves are pulsed to apply the desired depth of irrigation.

The system consists of a main controller, wireless nodes, solenoid valves and GPS. It is easy to retrofit or install on a new machine as it is being built.
