1. THE NOZZLE CHART METHOD OF CALIBRATION
a. Introduction
The Nozzle Chart Method (see sample below) is useful when the sprayer nozzles are
new or nearly new. It is also the most useful method to employ when the sprayer is
equipped with a Computer
Based Spray Control System
(CBSCS). The CBSCS does
most of the calibration work; it
is up to the operator to select
the proper combination of
nozzle size and ground speed,
which will deliver the desire
application rate.
The nozzle chart method
requires the use of the
appropriate nozzle charts,
which are found at the end of
this guide. (Nozzle Charts 1
through 7).
Nozzle charts are available for:
1. FIVE different types of nozzles:
a.
Spraying Systems Teejet Flat Fan
b.
Delavan Raindrop Hollow Cone
c.
Spraying Systems Turbo Floodjet
d.
Delavan Raindrop Flat Fan
e.
Spraying Systems Turbo Floodjet
2.
Three different nozzle spacings:
a. 10 Inch (25 cm)
b. 20 Inch (51 cm)
c. 30 Inch (76 cm) (Turbo Floodjet)
3.
Three different expressions of application rate:
a. US Gallons per acre (GPA)
b. US Gallons per 1,000 sq. ft. (GPT)
c. Liters per hectare (LPH)
NOTE: The information provided in the previous pages of this guide should help determine the
proper type of nozzle for your needs.
Nozzle charts for other nozzles are available from the manufacturer.
