OSCILLATING STRUCTURE METER Russian patent published in 2016 - IPC G01N11/14 

FIELD: instrumentation.

SUBSTANCE: oscillating circuit comprises a base, a casing, a loading device, a measurement device, a reservoir and a control unit. At the same time the loading device includes a reduction gearbox connected to a shaft of a stepped electric motor with transmission ratio of at least 20:1, at the outlet shaft of which there is a cam bushing fixed, to which a cam disc is fixed with screws with a through window arranged at its centre, and at the side of the bushing and symmetrically to its central axis, perpendicularly to the axis of longitudinal holes for screws, in it there is a slot of rectangular shape, where an eccentric with a splint is placed as capable of rotation, the tail of which with a gap is inserted into the central hole of the cam bushing. At the same time the disc of the cam contacts with a pusher installed coaxially to it in the central bushing attached vertically above it to the bracket of the base, and on the upper end of which there is a table with a reservoir fixed horizontally. The metering device comprises a sensitive element placed with a gap into the reservoir, arranged in the form of corrugated plates, attached with equal pitch along the circumference to the vertically arranged metering rod, fixed in a lock of a precision strain dynamometer installed on the bracket on the base.

EFFECT: simplified design and increased accuracy of measurements.
