Abstract: An apparatus for cumulatively measuring the weight of a continuous bulk material conveyed by a belt conveyer, comprising; a pulse generator operatively coupled to the conveyer for generating pulses of the frequency associated with the conveyer speed; a decimal counter for counting the speed associated pulses; a full scale detector coupled to the decimal counter; a load cell operatively coupled to the conveyer for providing an analog signal representative of the weight of the material within a predetermined span of the conveyor; an analog-to-digital converter responsive to the full scale output for converting the analog signal into a bit parallel coded digital signal; logical processing means for modifying the number of pulses obtainable from the decimal counter within one full scale of the counter as a function of the bit parallel coded digital signal and a cumulative counter for counting the pulses thus modified of the pulse number.
