Abstract:
1. A method for accommodating indirect ascertainment of fill-characteristics of fluid tanks on marine vessels, the method comprising the steps of: providing an experientially-based mapping of volume characteristics of a fluid tank positioned on a marine vessel correlated with respect to measurable fluid surface positions within the fluid tank; outputting fluid fill condition information for operator use based on quantification of a parameter other than sensed fluid level in the fluid tank based on a function of that other parameter being compared to the experientially-based mapping of volume; calibrating the accuracy of the output of fluid fill condition information by occasional adjustment of the map of volume characteristics versus measured fluid surface position; and assuring accuracy of the calibration by limiting execution of the calibration process to only when at least one of the following conditions is occurring: (a) the vessel is at a standstill, (b) the attitude of the vessel is substantially constant, and (c) fluid in the fluid tank is substantially static.
