A source vessel weight monitoring assembly for use in reactor systems to provide real-time and direct measurements of the availability of source or process materials from a source vessel. The assembly includes one or more force or load sensors, such as load cells, positioned between a bottom wall of the source vessel and a support element for the vessel (e.g., a base of a source vessel enclosure).
