FIELD: physics.
SUBSTANCE: flowmeter contains coaxial insert of preset diameter and lengths established in pipeline between which and pipeline wall the radial partitions forming longitudinal channels of identical section are designed. In three of these channels cylindrical pressure transducers with pressure heads in the form of three slots in two mutually perpendicular planes, passing through pipeline axis are mounted. Slots joints pipeline cavity with two internal chambers of pressure transducer and through pulse tubes with differential manometer. Two slots are connected with the first internal chamber. The third slot connected to the second internal chamber, is designed as incident flow.
EFFECT: higher accuracy of measurement; small overall dimensions and considerably reduced flow resistance.
