Choice of restrictor
As described previously it is important to have a flow as large as
possible in the filter, which is achieved by calculating the liquid con-
sumption to the spray boom. Read in the table under spray pressure
and pump type which restrictor should be used.
Example
A 361 pump and a 16 m boom are mounted on a sprayer. (Nozzle
spacing is 0,5 m i.e. 32 nozzles).
The nozzle which is used is 4110-20
The spray pressure chosen, 5 bar
In the nozzle table is read that the nozzle in question has a yield of 2.06
l/min at a pressure of 5 bar.
The total amount of liquid for the spray boom is:
32 nozzles x 2.06 l/min = 65,9 l/min 66 l/min
In the table refer to 5 bar and 361 pump. At a total amount of liquid of
66 l/min choose the GREEN restrictor.
