Radar Gauge
Set Volume Units
You may choose one of the following:
• Gallons (gal)
• Liters (L)
• Imperial Gallons (Impgal)
• Cubic Meters (cum)
• Barrels (bbl)
• Cubic Feet (cuft)
• Cubic Inches (cuin)
• Cubic Yards (cuyd)
Set Primary Variable
Select volume for volume measurements.
Set Range Values
(4 and 20 mA points)
When setting the range values, it is possible to enter the values directly or to
have the gauge read the values. If values are to be read by the gauge, set the
desired tank type first.
Choose Tank Type
Choose a tank with a standard shape, or select the strapping option. Standard
shapes: Vertical Cylinder, Horizontal Cylinder, Vertical Bullet, Horizontal
Bullet, or Sphere. (If primary variable is level, select “None”). If your tank is
not one of the above, or if you have strapping table information, select “Strap
Table.”
Enter Tank Dimensions
If a standard tank shape was chosen, enter the diameter and length
(or height) for the tank.
Enter Strapping
Table Information
(1)
First tell the gauge how many entries you will have; the more entries you
have, the better the gauge will be able to calculate the volume. The maximum
number of strapping points you can enter is 10.
Next, input the actual level and volume points, starting at the bottom of the
tank. It may be desirable to use most of the points in the areas of the tank that
are the least “straight.” See Figure 3-10. Suggestion: Set first entry at zero
level and zero volume to enable the gauge to track volume over the entire
range.
