For each tank type, as shown below, values for modes 31-34 must be entered.
If a mode is not indicated in the drawing, the value stored in that mode setting
will be ignored. For example, if tank type 4 is selected in Mode 28, only
Modes 31 and 34 will be used in calculations. Values in Modes 32 and 33 are
ignored. It is not necessary to set unused Modes to 0.
Conversion Factors
It is often desirable to display a volume output in units of measurement other
than cubic feet, inches, or meters. In order to do this you need to apply a
conversion factor. For tank types 2-5 the conversion factor needs to be entered
into modes 29- 30, and the DCR does the rest. For flat bottom tanks (type 1), the
conversion factor needs to be multiplied by the area of the bottom of the tank,
and the result entered into modes 29-30. This is only necessary for type 1 tanks.
Common Conversion Factors:
Cubic Feet (ft.
3 ) x 7.4805 = Gallons
Cubic Feet (ft. 3 ) x 28.317 = Liters
Cubic Inches (in. 3 ) x 0.00433 = Gallons
Gallons x 3.7854 = Liters
Common Area Formulas
(for use with type 1 tanks):
Area of a Circle = P x r
2
Area of a Square or Rectangle =
L x W
