ORION Wide Range: "precision" pesticide treatments

The Orion Wide Range ARAG flowmeter provides for the use of two integrated flowmeters in order to have a single control electronic unit and a diverter valve to select the flowmeter to be activated. Thanks to this innovation, which won a double recognition at EIMA 20/21, the Technical Innovation Award and the Blue Award, it is possible to equip the tool with a single electronic control system that measures very large flow rates.

ORION WR continuously measures the flow rate in the activated flowmeter and as soon as it exits the preset values, the fluid is diverted to the flowmeter with a higher or lower measuring range, as appropriate.

In addition to the cost savings, the control electronics common to both flow meters offers a single output for the two flow meters, making it compatible with all control systems currently on the market, which require the use of a single flow meter.

The device is composed of three interconnected blocks that can be summarized as follows: a 3-way ball diverter valve with the measurement tubes of the two electromagnetic flow meters, the control and measurement electronics, and the unification manifold for the delivery to the machine's line.

"On modern agricultural spraying and weeding machines, it is necessary to accurately dose the dispensed pesticides, which can change in a few seconds from the maximum flow rate, with all the nozzles open, to the minimum flow rate, with only one nozzle open.

Thanks to the Orion Wide Range technology - explains the Rubiera manufacturer in a technical note - it is possible to equip the machine with a single device capable of dosing a wide range of flow rates, with high accuracy across the entire scale (approximate accuracy of 1%) and with high reading accuracy.

Furthermore, the use of two flow meters offers reduced latency times, while the integration of the valve with the flow meter allows for automatic switching during the system adjustment phases".

Thanks to the innovative technology created by ARAG, the circuits for distributing pesticides are more precise, faster and able to adapt to different working conditions. Greater precision in the flow rate allows the sprayers to dispense the product in the most accurate way, thus avoiding those overdoses that can cause damage to crops and the environment, as well as simplifying the farmer's work.
