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.
A device 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 comprising, in combination, a conveying device for advancing the material at a speed having a known horizontal component, a movably mounted impact device having a surface for receiving material discharged from said conveying device in an impact direction such that the momentum of the material acting in the direction of said speed horizontal component exerts a horizontal force thereon, said impact device being arranged to reduce the speed horizontal component of the material in said impact direction to zero, discharge means for discharging the material from said impact device in a direction perpendicular to the direction of said speed horizontal component, a stationary support, and force measuring means mounted between said impact device and said stationary support for measuring said horizontal force of momentum to which said impact device is subjected by said material impacted thereon.
A method for continuously measuring a flow of material in mass per unit time by measuring the momentum ocurring by a change of movement of the material comprising the steps of, discharging flowable material from a source of supply, advancing said discharged flowable material in a path at a speed having a known horizontal component, impacting said moving flowable material onto an impact surface in an impact direction such that the momentum of said impacting material exerts a horizontal force on said impct surface in the direction of said speed horizontal component, reducing the speed of the impacting material in the direction of said speed horizontal component to zero with said impact surface, moving said impacting material from said impact surface in a direction perpendicular to the direction of said speed horizontal component and measuring said horizontal force exerted on said impact surface by said impacting material.
