Nozzle Flow-Rate
If the computer is not connected to a pressure transducer, it
may still be able to calculate and display the pressure on the
basis of the flow-rate value measured by the flow-meter and
the nozzle flow-rate data.
N.B. For correct pressure measurement, the nozzles must be
in good condition, so that the real flow-rate is the same as the
rated flow-rate.
If the operator is using nozzles which do not correspond to the
ISO standard, he can modify the default settings of the eleven
preset ISO nozzles.
This menu is accessed from the main menu screen by
pressing the
key for one second.
Use the
keys to locate on menu 4.0 (fig.10).
As can be seen, nozzle number 5 (red colour ISO 11004) is set
to deliver 0.8 litres/minute at a pressure of 3.0 bar. The opera-
tor can press the
and
keys to modify the flow-rate and
pressure value as appropriate to the nozzle in use.
To restore the ISO value, simply press the
key and confirm
the values with the
key.
See appendix for table 1, showing the relationship between
pressure and flow-rate for ISO nozzles.
Number of Nozzles
(467302 and 467304 versions only for 2- 4-way orchard
sprayers)
If the computer is installed on an orchard sprayer it is possible
to specify, according to requirements, the number of nozzles
used on each spray boom. By doing this the calculation of
pressure is more accurate if there is no pressure transducer
or the regulation is more stable if it is done referring to the data
read by the transducer.
You can access this menu from the main menu, press the
key for one second.
With keys
go to menu 5.0 (fig.11).
Press the
key and the keys
to select the spray
boom for which you want to set the number of nozzles.
Press key
to access data modification and set the number
of nozzles wanted by pressing keys
.
Press
to confirm the data and exit or
to exit without
changing the data.
