Title (EN) DEVICE FOR AUTOMATIC LOCATION OF POINTS OF LOSS IN A PRESSURE PIPELINE
(FR) DISPOSITIF DE DETERMINATION AUTOMATIQUE DE POINTS DE FUITE DANS UN PIPE-LINE SOUS PRESSION
Abstract: front page image
(EN)A device for automatic location of points of loss in a pressure pipe-line comprises a pick-up (1) with its output electrically connected to the input of an amplifier (6) whose output is connected with one of the inputs of a circuit AND (7) another input of which being connected with a pulse generator (8) whereas the output of the circuit AND (7) is connected to the input of an impulse counter (9). The device comprises as well an integrating unit (2) whose input is connected with the output of the pick-up (1), an amplitude limiter (3) whose signal input is connected to the output of the integrating unit (2), a limiting level control unit (4) with its output connected to the control input of the amplitude limiter (3), and a differentiating unit (5) whose input is connected with the output of the amplitude limiter (3) and the output - with the input of the amplifier (6).
(FR)Un dispositif de determination automatique de points de fuite dans un pipe-line sous pression comprend un capteur (1) avec sa sortie connectee electriquement a l"entree d"un amplificateur (6) dont la sortie est connectee a l"une des entrees d"un circuit ET (7), dont une autre entree est connectee a un generateur d"impulsions (8), tandis que la sortie du circuit ET (7) est connectee a l"entree d"un compteur d"impulsions (9). Le dispositif comprend egalement une unite d"integration (2) dont l"entree est connectee a la sortie du capteur; un limiteur d"amplitude (3) dont l"entree des signaux est connectee a la sortie de l"unite d"integration (2), une unite de commandes du niveau de limitation (4) avec sa sortie connectee a l"entree de commande du limiteur d"amplitude (3), et une unite de differenciation (5) dont l"entree est connectee a la sortie du limiteur d"amplitude (3), la sortie de l"unite de differenciation etant connectee a l"entree de l"amplificateur (6).
