Determining a pattern of arrival time cycle skip in an acoustic flow meter. At least some of the illustrative embodiments are methods comprising transceiving acoustic signals through a fluid flowing in a meter (the transceiving between respective pairs of a plurality of transducer pairs), measuring transit time of acoustic signals between the respective pairs of the plurality of transducers pairs, calculating a plurality of error values (each error value indicative of a cycle skip mode in measuring of the transit time of the acoustic signals), and determining the cycle skip mode using, at least in part, the plurality of error values.

La présente invention concerne la détermination dun modèle dun saut de cycle de temps darrivée dans un débitmètre acoustique. Au moins une partie des modes de réalisation illustratifs consiste en des procédés comprenant lémission et la réception de signaux acoustiques à travers un fluide circulant dans un compteur (lémission/réception entre des paires respectives dune pluralité de paires démetteurs-récepteurs), la mesure du temps de transit des signaux acoustiques entre les paires respectives de la pluralité de paires démetteurs-récepteurs, le calcul dune pluralité de valeurs derreur (chaque valeur derreur indiquant un mode de saut de cycle dans la mesure du temps de transit des signaux acoustiques) et la détermination du mode de saut de cycle à laide, au moins en partie, de la pluralité des valeurs derreur.
