VIBRATION LIQUID DENSIMETRE Russian patent published in 2009 - IPC G01N9/00 

FIELD: physics.

SUBSTANCE: proposed liquid densimetre contains a tubular resonator, support, joined to the resonator by jumpers, and a system for exciting and receiving oscillations, connected to the support. The support is joined to by jumpers and rigidly fixed relative the plane of symmetry of the tubular resonator. The tubular resonator and the support are made from material with low coefficient of linear expansion.

EFFECT: vibration densimetre for liquids, owing to the new design, which provides for invariance of mutual alignment of its main components in a wide temperature range; allows for high precision measurement of density of liquids.
