Abstract
A dispensing system and methods employed therein uses optical displacement sensing to control dispensation of one or more products. An optical displacement sensor measures displacement of a load beam supporting a vessel from which the product is to be dispensed. The displacement of the load beam is related to the amount (weight) of the product remaining in the vessel. The system may thus control dispensation of the product based on the optical displacement measurements.
