FIELD: measurement equipment.SUBSTANCE: flow meter comprises a pipeline and a drive, configured for vibration of a pipeline. Besides, the flow meter comprises the first sensor. The first sensor comprises the first component part of the sensor and the second component part of the sensor. The vibration flow meter also comprises a support part. The first component part of the sensor is connected to the support part, while the second component part of the sensor is connected to the pipeline near the first component part of the sensor. The vibration flow meter also comprises a balancing element attached to the support part. The balancing element is selected according to size and is arranged so that the mechanical moment of the element is substantially equal to and is opposite to or more than the mechanical moment of the active section of the support part. The support part comprises a support section adapted for vibrations near a bending axis, and a balancing element attached to the support part and adapted for vibrations around the bending axis substantially in antiphase with the active section.EFFECT: possibility to measure parameters under considerable variations of pressure and density of fluid medium.19 cl, 4 dwg |
