VORTEX FLOW CONTROLLER Russian patent published in 2007 - IPC G01F1/32 

FIELD: the invention is designed for measuring of volume consumption of liquid mediums in pressure pipelines.

SUBSTANCE: the vortex flow controller has two flowed-around bodies located one after another and having the same small distinctive size "d" with installed in them a sensitive element and a unit of outputting of a signal and a scheme of processing of output signals. The flowed-around bodies have profiles with smaller and larger coefficient of frontal resistance, at that the profiles of the flowed-bodies are chosen with providing inverse conduction of transmission coefficients of the measuring channels in the diapason of measuring of consumption. In the variant of execution before the flowed-around body with smaller coefficient of frontal resistance there is a flow turbulence promoter (for example, in the shape of cavities on the inner wall of the pipeline) and a flow rectifier is installed before the flowed-around body with the larger frontal resistance.

EFFECT: expands the diapason and increases accuracy of measuring including measuring in conditions of temperature changing of kinematic toughness, has increased reliability due to having two channels, small dimensions.
