Title (EN) APPARATUS AND METHOD FOR MEASURING THE FLOW VELOCITY OF A FLUID IN A PIPE
(FR) APPAREIL ET PROCÉDÉ DE MESURE DE LA VITESSE D'ÉCOULEMENT D'UN FLUIDE DANS UN TUYAU
Abstract:
(EN) An Apparatus (1) for measuring the flow velocity (Vmed) of a fluid (5) in a pipe (2), comprises a housing (3) in which a first ultrasonic transducer (TD1) and a second ultrasonic transducer (TD2) are arranged at a predefined distance (L) to each other, wherein said first ultrasonic transducer (TD1) includes a first sound transmitting element (4a) and a transmitter/receiver unit (6a) mounted thereto which are adapted to emit first ultrasonic pulses (P1) at different angles and said second ultrasonic transducer (TD2) is adapted to receive said first ultrasonic pulses (P1) and generate a first electronic output signal, and wherein the second ultrasonic transducer (TD2) includes a second sound transmitting element (4b) and a transmitter/receiver unit (6b) mounted thereto which are adapted to emit second ultrasonic pulses (P2) at different angles, and wherein said first ultrasonic transducer (TD1) is adapted to receive said second ultrasonic pulses (P2) and generate a second electronic output signal, a control and evaluation unit (8) electrically coupled to said first and second transducers (TD1, TD2). The control and evaluation unit (8) is adapted to tune the first transducer (TD1) to generate a first electronic output signal of a maximum amplitude, and tune the second transducer (TD2) to generate a second electronic output signal of a maximum amplitude, and is adapted to measure the flight time (T1) of the first ultrasonic pulses (P1) and the time of flight (T2) of the second ultrasonic pulses (P2) travelling between the first and second transducer (TD1, TD2). The invention is further related to a method for measuring different parameters of a medium and the pipe by means of the apparatus (1).
(FR) Selon la présente invention, un appareil (1) permettant de mesurer la vitesse d'écoulement (Vmed) d'un fluide (5) dans un tuyau (2) comprend un boîtier (3) dans lequel un premier transducteur ultrasonore (TD1) et un second transducteur ultrasonore (TD2) sont disposés à une distance prédéfinie (L) l'un par rapport à l'autre, ledit premier transducteur ultrasonore (TD1) comprenant un premier élément de transmission sonore (4a) et une unité émetteur/récepteur (6a) montée sur ce dernier qui sont aptes à émettre des premières impulsions ultrasonores (P1) à différents angles et ledit second transducteur ultrasonore (TD2) est conçu pour recevoir lesdites premières impulsions ultrasonores (P1) et pour générer un premier signal de sortie électronique, et le second transducteur ultrasonore (TD2) comprenant un second élément de transmission de son (4b) et une unité émetteur/récepteur (6b) montée sur ce dernier qui sont conçus pour émettre des secondes impulsions ultrasonores (P2) à différents angles, et ledit premier transducteur ultrasonore (TD1) étant conçu pour recevoir lesdites secondes impulsions ultrasonores (P2) et pour générer un second signal de sortie électronique, une unité de commande et d'évaluation (8) couplée électriquement auxdits premier et second transducteurs (TD1, TD2). L'unité de commande et d'évaluation (8) est conçue pour accorder le premier transducteur (TD1) de sorte à générer un premier signal de sortie électronique ayant une amplitude maximale, et pour accorder le second transducteur (TD2) de sorte à générer un second signal de sortie électronique d'une amplitude maximale, et est conçue pour mesurer le temps de vol (T1) des premières impulsions ultrasonores (P1) et le temps de vol (T2) des secondes impulsions ultrasonores (P2) se déplaçant entre les premier et second transducteurs (TD1, TD2). L'invention concerne en outre un procédé de mesure de différents paramètres d'un milieu et du tuyau au moyen de l'appareil (1).
