ABSTRACT:
Method and arrangement for accommodating indirect ascertainment of fill-characteristics of fluid tanks on marine vessels. The invention includes providing an experientially-based mapping of volume characteristics of a fluid tank positioned on a marine vessel that are correlated with respect to measurable fluid surface positions within the fluid tank. In consideration of this volume characteristic mapping, fluid fill condition information is output for operator use based on quantification of a parameter other than sensed fluid level in the fluid tank. While it is contemplated that the other parameter may be any characteristic that readily reads back to the volume characteristic mapping, it is particularly advantageous, and a preferred embodiment of the invention, that the other parameter be a volumetric quantification of fluid consumed out of the tank that can be compared to an earlier ascertained tank volume.
