11. Choose correction method.
There are several options available depending on gas mixture in the
tank. In the LPG Setup window click the Correction button to open the
LPG Correction window:
Choose one of the following correction methods:
a. Air Correction.
This method should only be used when there is no vapor in the tank,
i.e. when the tank is empty and contains air only. It is used in the
initial step when calibrating the 5900S.
b. One known gas.
This method may be used when there is only one gas type in the
tank. It provides the highest accuracy among the different correction
methods. Note that even small amounts of another gas reduces the
accuracy.
c. One or more unknown gases.
Use this method for hydrocarbons, for example Propane/Buthane,
when the exact mixture is not known.
d. Two gases with unknown mixratio.
This method is suitable for a mixture of two gases even if the
mixratio is not known.
e. One or more known gases with known mixratio.
This method may be used when there is a well known mixture of up
to 4 products in the tank.
Now the Rosemount 5900S level gauge is ready to measure the product level
when the tank is put into operation.
