Abstract
Method and apparatus for monitoring liquid stock in a storage tank. A prism connected by optical fibers is located at a fixed position in a tank, the volume of liquid at the fixed position being determined. A computer receives data relating to the liquid dispensed, and the liquid received, and calculates an amount of liquid in the tank at the moment the liquid passes the fixed prism. The calculated data is compared to the exact volume data received from the prism.
