Systems and methods that measure the total capacity for a plurality of storage tanks. Methods according to this aspect of the invention start with deriving a weighting factor for each one of the plurality of storage tanks, determining an overall transmitter resistance for the total capacity measurement, and multiplying each one of the storage tank weighting factors with the overall resistance yielding a span resistance corresponding to each one of the plurality of storage tanks. The method further includes coupling a transmitter mounted on each one of the plurality of storage tanks in a series loop whereby each transmitter has the span resistance corresponding to the tank mounted thereon and deriving a weighting factor includes adding the capacities of all of the plurality of storage tanks as a sum total capacity and dividing each storage tank capacity from the plurality of storage tanks by the sum total capacity.
