The weighing process uses a weighing pipe to which the bulk material is fed continuously, incorporating a shut-off slide cyclically opened and closed, with the increase in weight per unit of time being measured each time it is closed. The mean value is obtained from a large number of successive weighings and a computer is used for calculating the total amount of the bulk material flow. Pref. the duration of each closure cycle for the shut-off slide and hence each weighing internal is between 0.05 and 10 seconds, the intervals between the closure cycles pref. being freely selected in dependance on the bulk material flow stream.
