"VISIOBUSE" (patented by G R V) allows for the permanent and dynamic control of the performance of the nozzles of a sprayer. The signal is captured in front of each nozzle by an ultrasound sensor, linked to a miniaturized in-cabin indicator that provides the driver with information in real time. It can be adapted to all types of sprayer. It also contributes to the safety of the operator, who no longer needs to get out of the tractor to perform a visual check on the state of his nozzles (no inhalation of the product while the sprayer is working)
Management of the condition of nozzles during treatment ensures greater productivity, at the same time as reducing product dosages (without checks, no precision is possible).

Two versions of the system have been developed; a control and alarm version, in the event of a fault in one or more nozzles, and; a version that controls nozzle opening and closing timing. Stored on a USB device, the data are interpreted by computer so as to map plots and control treatment times and correct application.
