FIELD: physics.
SUBSTANCE: disclosed are inventions where cycle breakdown configuration during transmission and reception of signals in an acoustic flowmetre is determined, wherein transmission is carried out between corresponding converters of a group of pairs of converters. The propagation time of acoustic signals between corresponding converters of the group of pairs of converters is measured. A set error function values is calculated (each value of the error function is characteristic for the specific cycle breakdown configuration when measuring propagation time of acoustic signals) and the cycle breakdown configuration is determined using, at least partly, the set of error values.
EFFECT: high accuracy of determining signal cycle breakdown configuration in an acoustic flowmetre.
