FIELD: instrument making.
SUBSTANCE: at least some of displayed versions are methods that assume detection of reference time by a control facility, measurement of a liquid medium flow with the above flow metre, performing multiple measurements within a certain period of time, to produce various values of liquid medium flow (the flow metre is connected to the control facility), and also production of the flow metre value within the reference time, depending on the liquid medium flow. Total readings of the flow metre within the reference time, depending on the liquid medium flow, do not take into account the following: generation of a discrete output signal at the flow metre; and also the fact that the produced values of the flow metre are based on characteristics of the pulse sequence.
EFFECT: development of a method, a system and a flow metre for accurate detection of liquid medium flow in pipelines.
