Treatment Compatibility
Refer to Figure 14 (which depicts a bottom view of the meter
housing and gate, with gate retainer removed for clarity)
Flow rate is controlled by tapered opening
in the
adjustable gate.
Use only granular materials that flow easily and which
have a maximum particle dimension smaller than:
4.8 mm (
3 ⁄
16
inch, 0.19 inch)
maximum dimension. Materials larger than this cannot
pass through the slot in the meter housing, at any meter
setting.
Materials with a maximum particle dimension of:
1.4 mm (
3 ⁄
64
inch, 0.59 inch)
or less can flow at meter setting 5 and above.
Materials from 1.4 mm to 4.8 mm encounter a lower gate
setting limit at which they can flow. The material rate
goes to zero before reaching meter setting 10.
Reading a Treatment Rate Chart
Refer to chart excerpts at right.
1. Find the chart for your material and row
spacing .
Note: If there is no chart for your specific material, use
any chart and rely on Rate Calibration to determine
a final meter setting.
2. Find a column for the field speed at which you
intend to plant and/or apply treatment. If your exact
speed is not listed, rely on Rate Calibration to
determine final meter setting.
3. Find your intended application rate ( TargetRate in
the examples) in kg/ha or lbs/ac in the selected
speed column.
4. Find the suggested initial dial value in the Meter
Setting column. This is PriorDial in the examples.
Columns are also provided for single row rates. These
are useful for estimating sample sizes during Rate
Calibration, and may be useful should you desire to
create your own charts for alternate speeds.
The data at right is used in the example calibration
calculations on page 29.
