Irricontrol

21st Century Irrigation Management Tools for Progressive Farmers

is a basic electronic control system that can be fitted to most types of turbine or bellows driven hose reel irrigation machines to provide an accurate and constant rewind speed and various other features detailed below.

Irricontrol is normally powered by a 12V DC re-chargeable dry cell battery and a solar panel connected via a voltage regulator.

The length of hose unwound and the rewind speed can be measured directly from a roller on the hose or indirectly from a suitable sprocket on the drive system in which case the dimensions of the drum and the hose diameter have to be entered so that Irricontrol can automatically compensate for the build-up of hose on the drum as the hose is rewound.  All recent models of Irrifrance hose reels are preprogrammed and can be selected by name.

Irricontrol also includes a pressure sensor and two micro-switches to detect the end of an irrigation run or mis-coiling of the hose on the drum.

The duration of a run can be entered directly in hours and minutes, alternatively the desired speed can be entered and because Irricontrol includes a real time clock with day and date capability it will tell you the exact finish time and day of a run, as well as the remaining time in hours and minutes.

There is a built in calculator to work out the required rewind speed based on the application rate required, the raingun nozzle size and pressure and the spacing between runs.

Periods of irrigation with the raingun static at the beginning and end of a run (delayed start and stop) can also be independently programmed between 0 and 120 minutes.

Irricontrol is normally set to start automatically when the water pressure arrives but in the case of a pressurised system it can be connected to a live distribution main and be programmed to start up automatically at a set time on any day of the following week.

The Irricontrol is a user friendly device that communicates in English via an illuminated L.C.D. screen which guides the user through the programming sequence and displays helpful information in the event of abnormal operating conditions.

There is also a built in diagnostic program to test all of the sensors and solenoid valves in the event of maintenance being required.
