6.6 OPTIONAL ACCESSORIES
6.6.1 BRAVO 180S COMPUTER
Spraying computer, it regulates spraying based on working
speed. Each individual control is performed with dedicated
switch.
It controls up to 4 fan unit water sections and has a general
water section closing switch.
It displays: dosage (L/Ha), pressure, speed, instantaneous
flow rate, distributed amount, treated surface working time and
distance travelled.
It lets you modify spraying in litres per hectare during
treatment without stopping. Manual operation option.
6.6.2 BRAVO 140 COMPUTER
Electrical control for automatic control of cut-off valves opening
and closing based on the speed, detecting the presence of a
plant to be treated via ultrasound sensors with automatic com-
pensation of the solenoid valves opening and closing delays.
Each individual control is performed with dedicated switch.
It manages 2 water sections with 2 ultrasound sensors.
It displays: speed, surface treated, number of plants treated,
status of the ultrasound sensors.
Manual operation option.
For further details refer to the specific manual.
6.6.3 FLOW METER
The flow meter is an instrument suitable to measuring the liquid
flow to the fan unit. It has a minimum and maximum beyond
which the instrument loses its rated precision.
The Flow meter is characterised by a certain pre-set no. of
revolutions/litre. This value must be verified during the life of the
instrument, since it may vary depending on instrument wear.
There are two types: mechanical or electromagnetic induction.
The mechanical type features an impeller that rotates when the
liquid goes through and measures it by means of a revolution
counter sensor. The impeller must obviously not be hindered by
dirt. Such hindrance affects precision.
In the event of use at very low flow rate (under 10 l per minute)
replace with pressure switch (if supported by the computer you
have purchased) or use the manual computer function.
6.6.4 HOSE FOR CROP PROTECTION PRODUCTS
This is a kit connected to the pressure line of the machine able
to deliver directly from the hose an amount of pressurised phy-
toiatric mixture.
It may be supplied with hose winder and varying lengths of rub-
ber delivery hoses.
There are various types of nozzles: lever, machine gun, pistol.
For further details refer to the manual supplied in the package.
• The
lever nozzle
(Pic.119) is only controlled by the open-
ing lever (1) which delivers either a conical or pin-like jet
depending on how much it is pressed. The standard nozzle
is Ø = 1.5 mm.
• The
machine gun nozzle
(Pic.120) may deliver either
a pin-like or fully conical jet: the jet shape is selected by
pushing the lever (2) forward or backward. To open the jet
operate the lever (3). The standard nozzle is Ø = 2.5 mm.
• Pistol
(Fig. 121): technically similar to the others, it features
a one-hand grip and is supplied with a shorter hose.
Correct distribution of the crop protection product is directly
