FIELD: physics, measurement. ^ SUBSTANCE: invention may be used for determination of fluid medium density in different reservoirs, also in pressurised devices. Substance of invention consists in the fact that vibration probe comprising fork equipped with piezoelectric crystal fixed on bent section of fork, and magnetostrictive drive, additionally contains pipe and damping device. Damping device comprises bellows, sleeve and spring. Bellows is installed inside sleeve and tightly cut into vibration probe pipe, and spring is rigidly fixed to sleeve end and fork body. ^ EFFECT: higher accuracy of measurements. ^ 1 dwg |
