FIELD: measurement equipment.
SUBSTANCE: at least some part of the versions illustrating the invention represents flow metres consisting of a coupling determining a central fluid medium channel, the first group of pairs of converters installed on the coupling, the first control electronic circuit that is electrically connected to the first group of pairs of converters, the second group of pairs of converters installed on the coupling, the second control electronic circuit, which differs from the first control electronic circuit. The first and the second control electronic circuits are connected to each other and have the possibility of controlling the activation time of the corresponding pairs included in the above circuits of converters.
EFFECT: improving flow rate measurement accuracy.
