Apparatus and method for calibrating manifolded tanks

An apparatus for calibrating manifolded tanks, comprising:

• (a) sensors disposed within the tanks, said sensors sensing liquid levels in each of the tanks and providing first and second output signals;
• (b) at least one metering device for measuring the amount of liquid being dispensed into or out of the storage tanks and providing third output signals;
• (c) a processor having first and second inputs for receiving said first and second output signals, and a third input for receiving said third output signals, said processor being operative:
• i. to determine the dimensions of the tanks based on a first set of data values which represent estimates of the amount of liquid dispensed into or out of the combined tank corresponding to measured liquid levels in the tanks as sensed by said sensors, said processor being programmed with an algorithm for computing said first data values from said first and second output signals;
• and
• ii. to store a second set of data values derived from said third output signals, said second set of data values corresponding with actual volumetric quantities of metered liquid, which volumetric quantities are related to said measured liquid levels.
