Walking Speed (m/min)
Total Spray Volume (l/ha) = 10000 x Flow Rate (l/min) .
Walking Speed (m/min) x Band Width (ms)
Band Width (m)

Measure
your
Walking
Speed
in
meters
per
minutes
(m/min) by measuring
how many metres you
walk in one minute. As
a general rule one large
pace is approximately
one metre.
4. Measure
Band Width
in
meters (m)by spraying on
dry ground or concrete, and
measuring the width of the
spray pattern produced. It
is important that the nozzle
height from the ground is
the same
during spraying. If
spraying one row at a time, this
will be the distance between the
rows.
Flow Rate (l/min)
Calibration steps
1. Select nozzle
2. Measure
Flow Rate
in l per minute (l/min)
by measuring sprayer
output while pumping
over one minute).
You may find it helpful to use the working sheet on page 16 to
help you make your calibration calculations.
