A system tracks material flow during a production process. In particular, the system receives, from a materials container, a plurality of sensor readings. The materials container comprises a plurality of sensors at one or more intake locations and one or more outlet locations. The system generates an input data set and an output data set from the plurality of sensor readings. The system stores a first electronic ledger entry on an electronic ledger. The first electronic entry comprises the input data set and a time that sensor readings corresponding to the one or more intake locations were taken. The system stores a second electronic ledger entry on the electronic ledger. The second electronic entry comprises the output data set and a time that sensor readings corresponding to the one or more outlet locations were taken. The system generates display data associate with the first and second electronic ledger entries.
