GRAVITATIONAL VARIOMETER Russian patent published in 2006 - IPC G01V7/02 

FIELD: engineering of gravimetric equipment.

SUBSTANCE: device contains measuring system in form of identically oriented and rigidly interconnected two-coordinate indicators of horizontal components of gravity force acceleration (tilt indicators), distributed across horizontal and vertical coordinates. Measuring system is made in form of rigid square frame with indicators held in angles and suspended by means of flexible link connecting middle of upper rib to lid of upper cover, filled with liquid, without mechanical contact to its walls. Measuring system has negative floatability close to zero, and gravity center of device is positioned below its metacentre.

EFFECT: expanded functional capabilities of device, increased precision of measurements.
