MEASURING VIBRATION CONVERTER, APPLICATION OF MEASURING VIBRATION CONVERTER AND METHOD OF REDUCTION OF SENSITIVITY OF MEASURING CONVERTER TO PRESSURE

摘要

FIELD: measuring technique.;SUBSTANCE: measuring converter can be used in Coriolis mass flow meter. Converter as at least one measuring tube for letting flowing medium go, which tube is connected with pipeline through outlet branch pipe, inserted into input end, and outlet branch pipe, inserted into output end. Measuring tube makes bend oscillations around imagined axis, which connects inlet and outlet ends. Measuring tube has at least one arc-shaped section of preset volumetric shape. Arc-shaped section adjoins to corresponding straight section of tube at input and output sides. At least one ring-shaped rigidity member, serving for stabilization of volumetric shape, is fixed onto arc-shaped section or close to it, at straight sections. Lateral sensitivity of measuring converter to pressure inside measuring tube or to changes in pressure is reduced significantly by means of rigidity members.;EFFECT: improved precision of measurement; reduced cost of measurement.;29 cl, 3 dwg
