METERING CONVERTER OF VIBRATION TYPE AND APPLICATION OF METERING CONVERTER Russian patent published in 2009 - IPC G01F1/84 

FIELD: measurement equipment.

SUBSTANCE: group of inventions is related to the field of measurement devices, intended for measurements of fluid medium physical parametres (gas, liquid, powder or etc), sent by pipeline, and to their application. Metering converter comprises body (10), having multiple natural oscillating modes and at least one held in body (10) with the possibility of oscillations and at least temporarily vibrating first tube (4) for introduction of at least partial volume of measured medium. Besides metering converter comprises electromechanical, in particular electrodynamic device (60) acting at least at one pipe (4) for excitation and/or maintenance of mechanical oscillations of at least one pipe (4), and reacting to motions of pipe (4), in particular to bending oscillations, sensor device for generation of at least one metering signal (S_Vb), which represents oscillations of pipe (4). In order to improve oscillating properties (reduction of Y-efforts) and therefore accuracy of metering converter measurements, there are further provided at least three connecting elements (217) that connect between each other the first (4) and second (5) pipes on inlet side and at least three connecting elements (218) that connect between each other the first (4) and second (5) pipes from outlet side.

EFFECT: due to application of at least six connecting elements it is possible to make metering converters of vibration type of highly accurate measurements even with high conditional passages of more than 150 mm, in particular also with considerable preservation of structural shapes that already proved themselves.
