Step 3A
Complete the following steps to determine your retrieve rate (desired width).

Determine what inlet pressure is available while the sprinkler
is working.

Using Table 1 on page 10, find the closest width to what is
required. Be sure the inlet pressure shown for that row is
equal to or less than your available pressure.

The width noted in Table 1 is the wetted areas. This means
the sprinkler will project water approximately 15% further than
listed. This allows for proper coverage. For actual spray
diameter of the sprinkler refer to
Appendix A
– Sprinkler
Data on page 63.

Read nozzle size from the Table.

Choose the application depth, then read your retrieve rate in
inches per minute.
Example 1:
Using a 1100 traveller with an inlet pressure of 35 psi,
determine retrieve rate required to apply 1/2" to a 90 ft wide
area.

8 mm - 34 PSI - 90' width - 6.5 inches/minute

9 mm - 37 PSI - 92' width - 7.9 inches/minute
Step 3B
Complete the following steps to determine your retrieve rate
(known nozzle size).

Determine what inlet pressure is available while the sprinkler
is working.

Using Table 2 on page 10, find the nozzle and pressure
combination you are using.

Choose the application depth, then read your retrieve rate in inches per minute.

The width noted in Table 2 is the wetted areas. This means the sprinkler will
project water approximately 15% further than listed. This allows for proper
coverage. For actual spray diameter of the sprinkler refer to
Appendix A
–
Sprinkler Data on page 63.
Example 2:
Using a 1250 traveller with a 10 mm nozzle and an inlet pressure of 70 psi,
determine retrieve rate required to apply 3/4" to the irrigated area.
From Table 1, the following combination is identified:

10 mm - 70 PSI - 205' width
– 5.5 inches/minute
The battery will be
depleted at a quicker
rate
the faster the
retrieve rate is set.
For greater cycle life of
the
battery it is
suggested to use a
slower retrieval rate.
If the sprinkler is not
spraying
water, the
reading on the pressure
gauge will be higher
than
actual available
pressure. It is important
to have the sprinkler in
action to get a true
reading.
If the pressure at the
irrigation
sight is
inadequate you may
require a booster pump.
See page 57 for the
Cadman Booster Pump
option.
