FIELD: measurement equipment.
SUBSTANCE: flow meter comprises a first section of pipeline for the fluid routing from the main flow direction; a second section of pipeline for the fluid routing back to the main flow direction; a connecting pipe section for connection of the first pipeline section with the second pipeline section, at least one ultrasonic device for emitting and / or receiving ultrasonic waves; and a processing unit for measurement of transit time difference, and to determine the said parameter, and at least one vortex generating device is provided to form a vortex, located downstream of the said first pipeline section so that the formed vortex is directed opposite to the direction of the vortex formed downstream of the first pipeline section and upstream of the vortex device.
EFFECT: provision of improved repeatability of measurements of various structurally identical flow meters, reducing its sensitivity to the effects of disruptions in the flow.
