tab.
18. Choose the appropriate correction method for the product in the tank:
Option Description
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 Rosemount
5900S.
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.
One or more
unknown gases Use this method for hydrocarbons, for example Propane/
Buthane, when the exact mixture is not known.
Two gases with
unknown mixratio This method is suitable for a mixture of two gases even if the
mixratio is not known.
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.
