In the example on the previous page the
correct nozzle
for Tier 1 is the ALBUZ Brown operating at 7 Bar.
In the sample below, the
correct nozzle
for Tier 2 is
the ALBUZ Yellow operating at 7 bar. Note the formula
requires 0.84 L/min, and the nozzle flowchart shows
0.86 L/min. This nozzle with a marginal decrease in
pressure will meet our requirements.
Across the spraying season the variables (such as rates
and speeds) may often change. With a well setup system
small variations will be easily accommodated. Larger
variations may require a change of nozzles.
STEP 7 - FIT & TEST SELECTED NOZZLES
The most important calibration is to test for the actual
litres per hectare achieved through your sprayer.
• Use the following method to fit and test the selected
nozzles:
• Fit selected nozzles to the sprayer.
• Fill your spray tank to overflowing & set the specified
pump pressure and operate the sprayer for a short
period to make sure all lines are full and nozzles
are working properly (no blockages, leaks etc).
• Stop the sprayer and top up the tank with water to
overflowing again.
• Operate the sprayer in the stationary position at the
required pressure for not less than one minute.
• Measure how much water is required to refill the tank
to the brim.
• Now, divide the volume measured by the time taken
(minutes). The longer the test time the more accurate
the figure.
The calculation formulation is;
Output (L/min) =
Output (litres)
Time (minutes)
Example 1, testing Tier 1, refer page 59, step 1.
28.5 litres
1.25 minutes (75 seconds)
= 22.8 litres/min.
Which is slightly more than the target of 22.4L/min
(0.56 L/min per nozzle x 40 nozzles for 1.0 min)
Example 2, testing Tier 2, refer this page, step 1
.
42.1 litres
1.25 minutes (75 seconds)
= 33.7 litres/min.
(note 0.86 L/min per nozzle x 40 nozzles for
1.0 min = 34.4 L/min)
• Excessive output is a sign of worn nozzles.
See steps 8 & 9.
• Insufficient output is a sign of blockages.
See steps 8 & 9.
STEP 8 - CALCULATE THE ACTUAL
APPLICATION RATE
Actual application rate is the objective of setting up and
calibrating your sprayer.
