Methods and related systems for determining transducer delay time and transducer separation in ultrasonic flow meters. At least some of the illustrative embodiments are a method comprising measuring a delay time for a first transducer pair, measuring a total measured time for ultrasonic signals transmitted between a second transducer pair in an ultrasonic meter in which both the first and second transducer pairs are installed, calculating a parameter associated with the second transducer pair using the delay time of the first transducer pair and the total measured time for said second transducer pair.

La présente invention concerne des procédés et systèmes correspondants de calcul du retard propre des transducteurs et de l'intervalle entre transducteurs dans les débitmètres ultrasoniques. Pour certains modes de réalisation, le procédé consiste à mesurer un retard propre correspondant à une première paire de transducteurs, à mesurer un temps mesuré total pour les signaux ultrasoniques émis entre une deuxième paire de transducteurs dans un débitmètre à ultrasons dans lequel les deux paires de transducteurs sont installées, à calculer un paramètre associé à la deuxième paire de transducteurs en se référant au retard propre de la première paire de transducteurs et au temps mesuré total correspondant à la deuxième paire de transducteurs.
