Abstract
A novel powder flow rate measuring apparatus having a simple structure is described herein, in which a conveying fluid is injected through a nozzle into an inlet of a single detecting pipe line having an inlet and an outlet, also a powder material within a powder tank is introduced into the same inlet, and a pressure difference between the inlet and outlet of the detecting pipe line at this moment is detected, whereby a flow rate of the powder material flowing through the detecting pipe line can be measured. The thereby obtained measured value is essentially very close to a mass flow rate of the powder material, and moreover the measured value can be obtained continuously.
