Abstract

A measurement apparatus for measuring a flow rate of a powder includes a casing, a nozzle configured to dispense the powder, a fixture plate, a weighing scale, and a powder collector. The fixture plate includes a plurality of pinhole members. Each pinhole member includes a tip, a cylindrical hole extending from the tip, and a discharge passage. The cylindrical hole of each pinhole member has a diameter. The diameters of the cylindrical holes of the plurality of pinhole members are different from each other. The nozzle is configured to dispense the powder selectively into the cylindrical hole, and the powder collector is configured to receive at least a portion of the powder from the discharge passage.
