VIBRATION-TYPE MEASURING TRANSDUCER AND USE OF MEASURING TRANSDUCER IN BUILT-IN DEVICE Russian patent published in 2010 - IPC G01F1/84 

FIELD: physics.

SUBSTANCE: in the housing (100) of the measuring transducer of a built-in Coriolis flow metre there is an internal part comprising bent measuring pipe (10) for passing medium, which vibrates during operation, as well as a balancing device (20) fixed with formation of interfacing zones (11#, 12#) on the measuring pipe on the side of the inlet and on the side of the outlet. The internal part is mounted with possibility of vibration in the housing of the transducer using connecting tubular elements (11, 12), through which the measuring pipe (10) is connected to a pipeline during operation. The balancing device is formed by two plates (21, 22) lying on the side of the measuring pipe, the height of each of which monotonously falls from the interfacing zone to the middle of the section of the balancing device. Owing to realisation and orientation of the measuring pipe and the balancing device, the centre of gravity M₁₀ of the measuring pipe lies from longitudinal axis (L) further than the centre of gravity of M₂₀ of the balancing device.

EFFECT: invention provides dynamic balancing in a wide range of medium density with simultaneous reduction in the weight of the measuring transducer.
