Introduction:

Guarding and controlling the transfer of different fuels has always been of interest to marketers, with the measurement process involved, where it is expected to obtain results with the least possible error. Therefore the consideration of uncertainty, in conjunction with the techniques for quality control play an essential role.

Objective:

To evaluate the process of reception, storage and delivery of fuels through the proposal of a methodology that guarantees its efficiency with the use of quality control tools and the traceability and uncertainty analysis.

Materials and Methods:

Taking as an example the transfer of liquefied petroleum gas (LPG) in a base unit, using the cause-effect diagram, Pareto analysis, control charts and the estimation of uncertainty with the analysis of the traceability of the process, the fuel balance is performed for obtaining the profit-loss ratio.

Results and Discussion:

There are failures in the transfer chain because of using inadequate instruments that cause instability in measurement. A new profit-loss ratio is defined with the proposed methodology that guarantee reducing losses from $ 24 887.2 (53 208 L of LPG) to zero.

Conclusions:

The new value of the profit-loss ratio allows obtaining logical results, totally reducing the non-completion of the deposit.
