METERING CONVERTER OF VIBRATION TYPE Russian patent published in 2010 - IPC G01F1/84 G01F15/18 

FIELD: measurement equipment.

SUBSTANCE: metering converter of vibration type comprises at least one combined multi-metal system (1, 2). The first part (1) of combined system is arranged in the form of composite formed component, which consists of at least two materials, which differ from each other by at least one physical and/or chemical property: density, melt temperature, coefficient of thermal expansion and/or elasticity module. Each of part (1) materials constitutes at least 1% of its volume. One of materials of the first part at least by one physical and/or chemical property is identical to material of the second part. Parts (1,2) of combined system are at least partially connected to each other by means of soldered and/or welded joint. Version of combined system comprises the third part made identically to the first part (1) and fixed onto the first part and/or the second part (2). One of parts (1,2) of combined system of Coriolis flow metre is arranged in the form of metering pipe that makes bending oscillations, the second one - in the form of disk-shaped body fixed on pipe, and third one - in the form of bearing element: body, response vibrator, coaxial to metering pipe, or flange. At least one of parts (1,2) partially consists of steel, or titanium, tantalum, zirconium or their alloys.

EFFECT: strength of mechanical joint in case of durable operation and considerable simplification of manufacturing.
