FIELD: instrumentation.
SUBSTANCE: measuring system is used for measurement of density and/or weight flow rate of the medium flowing in the pipeline, at least, from time to time. For this purpose the measuring system contains the measuring vibration type sensor for creation of oscillatory measuring signals, and also the electronic unit of the converter electrically connected to the measuring sensor for control of the measuring sensor and for processing of the oscillatory measuring signals which are supplied by the measuring sensor. It has a sensor housing (71) the first housing end of which from the inlet side is formed by means of a flow divider (201) with exactly four respectively spaced flowing holes (201A, 201B, 201C, 201D) from the inlet side, and the second housing end from the outlet side is formed by means of the flow divider (202) with exactly four spaced flowing holes (202A, 202B, 202C, 202D) from the outlet side; exactly four, at forming of hydraulically parallel connected flow paths, measuring pipes (181, 182, 183, 184) connected to flow dividers (201, 202) for guiding of the flow medium; an electromechanical excitement configuration (5) formed by means of the first oscillation activator for generation and/or sustaining of mechanical oscillations of four measuring pipes (181, 182, 183, 184) which also reacts to vibrations of the measuring pipes (181, 182, 183, 184), the configuration (19) of vibration sensors for generation of self-expressing vibrations of the measuring pipes (181, 182, 183, 184) of oscillatory measuring signals. Each of measuring pipes has a middle segment amounting, at least, 40% of its length in which the named measuring pipe has no mechanical connection with other measuring pipes and/or where it is freely moving with reference to other measuring pipes. The useful mode actively excited by means of excitement configuration of the oscillations devices is also the natural mode of flexural oscillations named as V-mode and which is inherent to the configuration of pipes.
EFFECT: improvement of stability of measuring system.
