CORIOLIS MEASUREMENT DEVICE Russian patent published in 2014 - IPC G01F1/05 

FIELD: measurement equipment.

SUBSTANCE: invention proposes a Coriolis measurement device that is additionally equipped with an exciter of torsional vibrations, a receiver of torsional vibrations, an evaluation unit of transfer function of torsional vibrations with an approximation unit of transfer function of torsional vibrations, which is connected to its output, as well as a temperature evaluation unit. With that, a generator of broadband signals is of a two-channel type which provides generation in the first channel of a signal in vicinity of resonant frequency of bending vibrations, and in the second channel - in vicinity of resonant frequency of torsional vibrations. Besides, the output of the second signal is connected to an exciter of torsional vibrations; the receiver of torsional vibrations is connected to the input of the computing unit of transfer function of torsional vibrations; inputs of the temperature computing unit are connected to the corresponding outputs of the approximation units of bending and torsional vibrations, and its outputs are connected to the corresponding inputs of the computing units of transfer function of bending and torsional vibrations; with that, in inlet and outlet connectors there are slots on the inner side symmetrically between flow meter tubes; each of the exciter and the receiver of torsional vibrations is made in the form of two opposite-phase connected piezoelectric elements mounted symmetrically between the flow meter tubes into the slots of the corresponding connectors, and sensor receivers are made in the form of piezoelectric plates mounted into central areas of the corresponding slots.

EFFECT: improving accuracy and stability of measurements.
