Abstract
A spray distribution measuring device comprises a chamber 4 having a spray nozzle 1 as a measurement object at the top; a saucer 3 arranged below the spray nozzle within the chamber 4 and partitioned into a plurality of regions each having a prescribed area; measuring tubes 6 each installed substantially vertically from each region of the saucer 3 and having a prescribed sectional area, the upper end of each of which opens into the bottom of each region of the saucer; pressure sensors 7 each installed at the lower end of each of the measuring tubes to measure the head pressure of each measuring tube; and a controller 10 for computing a difference between the pressure applied to the pressure sensor and an initial pressure, and measures the spray distribution on the basis of a difference between the head pressure of the a test solution accumulated in each measuring tube by spraying and the initial pressure before the spraying.
