A mass flowmeter, comprising: a casing (18), two U-shaped measurement tubes (1, 2) located in the casing (18) and having an identical structure, vibration exciters (3) installed at the central axe of the two U-shaped measurement tubes (1, 2), detectors (4, 5) respectively located at the center of second partial arc segments (22, 23), four spacing plates (6, 7, 8, 9), two flanges (10, 11) respectively and symmetrically disposed at the two outermost ends of the mass flowmeter, two end connecting tubes (12, 13) connected with the two U-shaped measurement tubes (1,2) via two splitters (14, 15), and a lead wire connector (17). The two splitters (14, 15) are connected to each other via a middle connecting tube (16); the two U-shaped measurement tubes (1, 2) are disposed in parallel; the U-shaped measurement tubes (1, 2) comprise a first partial arc segment (19); the two sides of the first partial arc segment (19) are respectively and sequentially connected to oblique tube segments (20, 21), the second partial arc segments (22, 23), and straight tube segments (24, 25); and the left and right parts of the U-shaped measurement tubes (1, 2) are symmetrical relative to the centerline of the first partial arc segment (19). |
