Meter Pressurization (U.S. customary units)
Corn: Reading a Pressure Chart (below, next page)
1.
Pick the chart based on seed shape (flat, round).
Example: large round corn
2. Pick a line based on seed size (large, small).
Example: the right line below
3. Find the seed density on the bottom scale.
Example: 1260 seeds/pound
4. Read the suggested starting pressure on the left
scale, where the line (example shown as dotted
gray) intersects the density.
Example: 3.4 inches of water
