Abstract

Particulate bulk material stored in a silo (10), in particular in a Hogan Bin Discharger, has its weight measured by agitating the material (during of after filling) using fluidising air nozzles (26), measuring the pressure on a floor mounted frame member (14) by means of a strain gauge (16), and using a processor (36 etc.) to calculate the weight of the material by multiplying the pressure by the known area of the silo.
