MASS FLOWMETER Russian patent published in 2017 - IPC G01F1/84 

FIELD: physics, measurement technology.

SUBSTANCE: present invention relates to a measuring device, more specifically to a U-shaped Coriolis mass flowmeter. The mass flowmeter comprise a housing (18), 2 identical U-shaped measuring pipes (1, 2), installed in the housing (18) and having an identical structure, vibration exciters (3) installed on the centre axial line of the two U-shaped measuring pipes (1, 2), detectors (4, 5), respectively arranged in the centre of segments (22, 23) of the arc of the second portion, four collets (6, 7, 8, 9), two flanges (10, 11), respectively and symmetrically arranged at the outermost ends of the mass flowmeter, two end branch pipes (12, 13), connected to the two U-shaped measuring pipes (1, 2) by current dividers (14, 15) and an input connector (17). The two current dividers (14, 15) are connected to each other using an intermediate branch pipe (16); the two U-shaped measuring pipes (1, 2) are arranged in parallel; wherein the U-shaped measuring pipes (1, 2) comprise a segment (19) of the arc of the first portion, wherein at both sides of the segment (19) of the arc of the first portion separately and successively there are connected inclined portions (20, 21) of pipes, segments (22, 23) of the arc of the second portion and portions (24, 25) of the straight pipe; and the left- and right-hand halves of the U-shaped measuring pipes (1, 2) are symmetrical with respect to the centre line of the segment (19) of the arc of the first portion.

EFFECT: invention reduces the impact of the flow field on measurement, reduces flow resistance, reduces pressure loss, simplifies the apparatus and processing, provides good dynamic equilibrium properties, improves overall efficiency, and provides a wide measurement range and enables measurement of mass flow of a liquid with high viscosity and high content of impurities.
