Menu 3.4.3 Nozzle size flow at 3 bar
This menu can be used for two different scenarios:
Check of nozzle output for
nozzles used.
In case of flow sensor and/or
pressure sensor fault.
• Default value: 0.40 l/Min
μ
ATTENTION! If changing nozzles while a sensor is faulty,
then type in the size of the new nozzle.
The nozzle size is defined as the flow at 3 bar, as to be seen in the
HARDI nozzle catalogue.
÷
NOTE! The flow at 3 bar in the HARDI nozzle catalogue is
measured without the nozzle filter and without the
PENTALET nozzle holder. The flow restriction from these 2
make the nozzle appear smaller, see table below.
Nozzle

010-Orange

05-Brown

08-White
10-Light blue
15-Light green
In fault-free operation, the controller use the flow sensor and the pressure sensor to
detect the nozzle size.
Therefore, when entering this menu while spraying, the actual nozzle output is
calculated and shown in the display.
This can be used when nozzles are changed or e.g. to check the nozzle output when a
specific gravity has been set in menu 3.5.1 for fertilizers.
The nozzle flow can be entered to obtain an more accurate regulation of the regulation
valve.
If either the flow sensor or the pressure sensor is faulty, the nozzle cannot be identified.
The controller stores the last detected nozzle size, and this value is then used.
