Novel metal tube rotor flow meter device

The utility model relates to the technical field of metal tube rotor flow meter production, and discloses a novel metal tube rotor flow meter device which comprises a supporting table, and a fixing mechanism is arranged at the top end of the supporting table. The fixing mechanism comprises a first threaded rod and a second threaded rod, the first threaded rod is rotationally connected to the top end, close to one side, of the supporting table through a first bearing, the second threaded rod is rotationally connected to the top end, close to the other side, of the supporting table through a second bearing, and the outer wall of the first threaded rod is fixedly sleeved with a driving wheel. The metal tube rotor flow meter can play a role in fixing and pressing the flow meter body, ensures that sampling values of the flow meter cannot shake and frequently change due to the stability problem, and solves the problems that when an existing metal tube rotor flow meter calibrates the sampling values, a floater and a
