Volume of a fluid in a tank is determined by measuring the pressure of fluid proximate to the bottom of the tank. The depth of the fluid is then determined from the pressure and density of the fluid. Fluid volume is then determined mathematically or from charts given the depth as well as the size and shape of a tank. Multiple pressure readings may be taken along the bottom of a tank, and an average pressure determined that may be used to calculate volume. Pressure readings may be taken at different heights to determine fluid density used to calculate volume. Pressure readings may be adjusted for atmospheric pressure. Volume increases or decreases exceeding a respective predetermined threshold may be flagged and alerts generated. Volume calculations may be recorded for comparing against a volume of fluid recorded as being purchased.
