FIELD: instrument making.
SUBSTANCE: measurement system, to inlet end of which supply section (400) of process pipeline is connected, comprises a measurement converter, which includes measurement tube (2) serving to transfer measured medium, where sensor with at least one sensitive element is installed. Measurement electronic equipment is joined to measurement converter. At inlet end of measurement tube there is a flow shaper (300) with clear space narrowing in direction of tube (2). At least one inner edge closed along circumference protruding into clear space of shaper (300) limits surface of collision arranged in end area of flow shaper and providing for formation of at least one stationary toroidal swirling inside medium flowing by specified edge. Sensor may be represented by vortex sensor of flow rate, magnetic inductive sensor of flow rate, flow rate sensor of vibration type (in particular, Coriolis transducer of mass flow), ultrasonic flow rate sensor, density sensor, viscosity sensor.
EFFECT: increased accuracy of measurement under conditions of possible disturbances in fluid medium at feeding section of process pipeline at minimum assembly length of measurement system.
