ABSTRACT:
A device and a method for continuously measuring a flow of material in mass per unit time by measuring the momentum occurring by a change of movement of the material utilizing a conveyor to advance the material undergoing measurement at a speed having a known horizontal component. A catching box is movably mounted to serve as an impact device and presents a surface for receiving the material as it is discharged from the end of the conveyor. The discharged material exerts a horizontal force on the catching box which, in turn, causes the speed horizontal component of the material to be reduced to zero. The material is discharged from the catching box in a direction perpendicular to the direction of said speed horizontal component. A force measuring instrument is mounted between the catching box and a stationary support and serves to measure the horizontal force of momentum to which the catching box is subjected by the material impacting upon it.
