DEVICE FOR MEASURING HYDRAULIC ROUGHNESS OF A PIPELINE INTERNAL SURFACE |
摘要 |
The inventive device (1) for measuring the hydraulic roughness of a pipeline (2) internal surface comprises a carriage (4) provided with wheels (3). A drum (5) is rotationally mounted on the carriage (4). The roughness is determined on the basis of the measurement of a resisting moment of the drum (5) or a dynamic pressure measurement by Pitot tubes (11). The translationally movable carriage (4) makes it possible to perform measurements at the different points of the tube (2). |
