  • Process mass flow apparatus and method for measuring the mass flow of powdered and granulated solids as well as the accumulated weight of material passed during a specified time
    Patent number: 6367336
    Abstract: A process mass flow apparatus for measuring the mass flow rate of a powdered, granulated or otherwise substantially divided process solid, seeds, grains, or similar particulate materials includes a process material inlet, a process material outlet, a measuring chamber connecting the process material inlet and the process material outlet, comprising a movable element with a fixed axis of rotation located in the flow path of the process material and having attached to the axis of rotation a material flow sensor which provides a raw output signal corresponding to an unknown mass flow rate and a processor which contains an empirically derived calibration function for converting the raw output signal to an adjusted signal indicating the mass flow rate of the process fluid.
