FIELD: physics. ^ SUBSTANCE: rate-of-flow indicator contains a pair of flow measuring tubes executed with possibility of vibration in antiphase concerning a plane of symmetry, vibrating system of excitation containing the first reel component and the second magnet component which are attached to corresponding flow measuring tubes. The first and the second components of the vibrating excitation system have identical sizes and are located in such a manner, that general centres of masses of the first and second flow measuring tubes and the first and second components are, accordingly, on the first and second planes of equalisation, parallel the mentioned plane of symmetry. Thus the end nodes of both flow measuring tubes are placed on the equalisation planes. ^ EFFECT: improvement of Coriolis acceleration flow metre structure balance in Y-direction. ^ 11 cl, 9 dwg |
