DEVICE FOR DETERMINING AND/OR CONTROL OF PHYSICAL PARAMETERS OF FLUID Russian patent published in 2007 - IPC G01F23/296

Abstract RU 2310818 C2

FIELD: measuring technique.

SUBSTANCE: device comprises at least one mechanical vibration unit and at least one driving/receiving unit. The driving/receiving unit excites vibration of the vibration unit (or receives the vibration of the vibration unit) and has at least one piezoelectric drive having at least one outer surface. The outer surface is composed of at least two segments of different polarization.

EFFECT: enhanced precision.
