PRELIMINARY

VOLUME 

CONFIGURATION

Transmitter Variables

Select the Volume option in order to configure the transmitter for volume 
measurements.

Volume Units

Choose one of the following units:

• Gallons
• Liters

• Imperial Gallons

• Cubic Meters
• Barrels

• Cubic  Yards

• Cubic Feet
• Cubic Inch

Tank Type

Choose a standard tank shape, or select the strapping option. Standard 
shapes are: Vertical Cylinder, Horizontal Cylinder, Vertical Bullet, Horizontal 
Bullet or Sphere. (If Primary Variable is Level choose None for Tank Type).

If your tank does not correspond to any of the above tank shapes, select Strap 
Table.

Tank Dimensions

If a standard tank type was chosen, enter the diameter and height of the tank. 
See “Volume Configuration” on page 5-6 for information on how to specify 
tank dimensions.

Strapping Table

If tank type Strapping Table was chosen, enter how many entries you will use 
and the actual level and volume points. You can enter from 2 to 10 points. The 
strapping points must be entered such that the first point corresponds to the 
lowest level, and the last point corresponds to the topmost level of the tank.
