Abstract
A shelf assembly for tracking the weight of non-homogeneous products stored thereupon in a refrigerator comprises a weighing base comprising opposing load-cell bases detachedly attachable to respective left and right internal walls of the refrigerator, a shelf frame or at least one beam member joining respective said opposing load-cell bases so as to form, in combination therewith, a rigid shelf frame, the rigid shelf frame being open to a vertical airflow over at least 25% of its horizontal surface area; a shelf open to a vertical airflow over at least 50% of its horizontal surface area; and a plurality of load cell assemblies fixedly attached to each of respective said opposing load-cell bases so as to mediate between the load-cell bases and the shelf. The shelf can be a wire-grid shelf.
