項に記載の質量流量計。[Claims for Utility Model Registration] (1) A curved conduit supported near an inlet and an outlet and symmetrical to an axis passing between the support points is driven in a direction perpendicular to the surface of the curved conduit, and the single In a mass flowmeter that measures the Coriolis force proportional to the angular velocity around the axis and the flow velocity due to vibration drive, and determines the mass flow rate of the fluid proportional to the Coriolis force, part or all of the curved conduit is A mass flowmeter characterized by being constructed from a small piece of glass or the like. (2) Utility model registration claim No. (1) characterized in that the curved conduit is a U-shaped tube, and only the straight pipe portions on both sides of the U-shaped tube are glass tubes with a small coefficient of thermal expansion.
Mass flow meter as described in Section.
