FIELD: physics, measurement.
SUBSTANCE: flow metre includes case in the form of pipeline section, reducer device in the form of tube with nozzle, jet feedback generator with piezo electric converters installed in feedback channels, sealing cap and hold-down nut. Jet feedback generator is made in the form of flat disk with through perforated slots and mounted on basement connected leakproof to pipeline. Inlet and outlet channels of jet feedback generator are made in the form of orifices in lower basement part and upper pipeline part, overlapping with inlet nozzle and work chamber of feedback generator respectively.
EFFECT: enhanced precision of measurement, simplified manufacturing technology.
