FIELD: measuring equipment.
SUBSTANCE: sensor comprises a housing (71) of the sensor in which the first end of the housing on the side of the inlet is formed by the first flow divider (201) having strictly four each spaced apart flow ports (201A, 201B, 201C, 201D), and the second end of the housing on the side of the outlet is formed by the second flow divider (202) having strictly four each spaced apart flow ports (202A, 202B, 202C, 202D), and strictly four generating hydraulically connected in parallel flow paths, the direct measurement tubes (181, 182, 183, 184) connected to the flow dividers (201, 202) for passing the fluid carrier. Each of the four measurement tubes enters from the corresponding side of the inlet with the corresponding end of the measurement tube into one of the flow ports (201A, 201B, 201C, 201D) of the first flow divider (201) on the side of the inlet and with the corresponding end of the measurement tube on the side of the outlet to one of the flow ports (202A, 202B; 202C, 202D) of the second flow divider (202) on the side of the outlet. In addition, the sensor comprises the electromechanical driver circuit (5) for producing and/or maintaining mechanical vibrations of four measurement tubes (181, 182, 183, 184), and configured so that the measurement tubes are actuated in pairs in antiphase bending vibrations in the common virtual plane of vibration (X, XZ2).
EFFECT: providing an acceptable pressure drop over the wide range, especially at very high proportions of mass flow.
