FIELD: the invention refers to the field of instrument-making.
SUBSTANCE: the flowmeter has a flowmeter tube whose transversal vibrations are excited with a drive. The inner part of the tube is formed with an element in the shape of a spiral making rotation of the flow inside the tube. The value of deviation of the flowmeter tube in the first mode under the action of the gyroscopic forces is connected with the value of mass consumption. In the process of the work of the flowmeter one can determine the forces of Coriolis which are formed with the flow of material in vacillating flowmeter tube in the second mode and bring it to cyclical deformation in the plane of the drive. The information received in the both modes is transferred on electronic measuring device which uses it for comparison and putting in necessary corrections at finding mistakes.
EFFECT: the inventions provide an increase of accuracy in conditions of changing the density of material with using of simple and cheap electronics equipment.
