Abstract: A technology to measure the mass flux distribution of liquid spray to evaluate droplet dispersion of a spray device for liquids such as fuel, paints, or coating agents, is provided. The apparatus for measuring spray mass flux to evaluate the droplet dispersion of the spray device includes a liquid spraying part including a spray nozzle to spray liquid, a spray collecting part to collect the liquid sprayed from the liquid spraying part, a transfer tube to transfer the liquid collected in the spray collecting part, a multi-cylinder part including a plurality of cylinders to receive the liquid collected in the spray collecting part, a movable mass measurement part to measure a mass of each cylinder of the multi-cylinder part, and a mass flux calculating part to calculate a distribution graph of mass flux of the sprayed liquid.
