Title (EN) DEVICE FOR LOCATION OF POINTS OF LOSS IN A PRESSURE PIPE-LINE
(FR) DISPOSITIF DE DETERMINATION DES POINTS DE FUITE DANS UN PIPE-LINE SOUS PRESSION
Abstract: front page image
(EN)A device for location of points of loss in a pressure pipe-line comprising two converters (1, 2) for converting mechanical oscillations into electric ones, the outputs of both converters being electrically connected with an indicator (10). The device comprises as well a variable delay unit (6), a multiplying unit (8) the first input of which is connected to the output of the variable delay unit (6), an integrating unit (9), the input of which is connected to the output of the multiplying unit (8) and the output-to the input of the indicator (10), and a switch (3) intended for connecting, in one of its positions, the output of the first converter (1) to the output of the variable delay unit (6) and the output of the second converter (2) to the second input of the multiplying unit (8), and, in another position, the output of the first converter (1) to the second input of the multiplying unit (8) and the output of the second converter (2) to the input of the variable delay unit (6).
(FR)Un dispositif de determination des points de fuite dans un pipeline sous pression comprend deux convertisseurs (1, 2) pour convertir des oscillations mecaniques en oscillations electriques, les sorties des deux convertisseurs etant connectees electriquement a un indicateur (10). Le dispositif comprend egalement une unite a temporisation variable (6), une unite de multiplication (8) dont la premiere entree est connectee a la sortie de l"unite a temporisation variable (6), une unite d"integration (9), dont l"entree est connectee a la sortie de l"unite de multiplication (8) et la sortie de l"unite d"integration est connectee a l"entree de l"indicateur (10), et un commutateur (3) servant a connecter dans l"une de ses positions la sortie du premier convertisseur (1) a la sortie de l"unite a temporisation variable (6) et la sortie du second convertisseur (2) a la seconde entree de l"unite de multiplication (8), et servant a connecter, dans une autre position, la sortie du premier convertisseur (1) a la seconde entree de l"unite de multiplication (8) et la sortie du second convertisseur (2) a l"entree de l"unite a temporisation variable (6).
