PRAY COMPUTER
§3.3.1 General
The FMC spray computer ensures that the application rate in litres per hectare, regardless of the
driving speed and current working width, always precisely matches the programmed nominal
value.
The computer permanently calculates the necessary flow of liquid (l/min) which must be conveyed
to the nozzles on the basis of the programmed application rate (l/ha), the current driving speed
(km/h) and the currently active working width (m).
The necessary flow of liquid Q (l/min) can be calculated with the following formula:
working width (m) x driving speed (km/h) x application rate (l/ha)
600
The flow of liquid calculated in this way is compared with the actual flow of liquid flowing to the
nozzles at the present time by the electronics.
This actual value is established by a flow meter installed between the pressure regulator and the
section valve block.
If the actual through flow quantity deviates from the calculated through flow, the pressure regulator
is actuated until the two values are identical again.
This measurement and regulation process permanently takes place with the result that the flow of
fluid is immediately regulated by the pressure regulator if the driving speed or the active working
width (section switching) are altered. The application rate in litres per hectare always remains
constant.
The required quantity (nominal value) can be adjusted by the driver at any time while driving. It is
also possible to adapt the quantity at certain places on the field. A touch of a button is sufficient to
switch back to automatic operation, with automatic regulation to the programmed nominal value
resulting.
The FMC spraying computer also has a warning system, which emits a signal if an upper or a
lower limit for the spraying pressure is reached. A warning signal is also emitted if a certain.
programmable liquid level in the spray tank is fallen short of.
The computer also permanently computes the remaining area or the remaining distance which can
be sprayed with the amount of fluid currently in the container.
The sprayed area and consumed amount of liquid can be stored for up to 20 parcels of land.
