In a pressure loss device in which a perforated plate for pressure loss is installed in a direction perpendicular to the flow inside the main body connected to piping, the distribution of holes drilled in the perforated plate for pressure loss is determined. The perforated plate is installed in the main body so as to be movable in the direction perpendicular to the flow, and the number of holes in the perforated plate located in the inner diameter of the main body is changed by the movement of the perforated plate. A pressure loss device comprising a perforated plate, characterized in that it is adapted to obtain a matched pressure loss. 2. The porous plate according to claim 1, wherein the porous plate for pressure loss is formed in an elliptical shape extending through the main body, and is composed of porous portions opened at regular intervals and portions without holes. A pressure loss device consisting of a plate. 3. A pressure loss device comprising a perforated plate according to claim 1 or 2, characterized in that a plurality of perforated pressure loss plates are movably arranged in parallel inside the main body at regular intervals in the axial direction.
