特徴とするコリオリの力式流量計。 A pair of curved conduits of approximately the same shape and size are supported in parallel with an axis perpendicular to the flow tube axis as a symmetry axis, and the fluid flowing through the flow tubes is divided into equal flow rates to each curved conduit. In a flowmeter that vibrates a curved conduit in a tuning fork shape and obtains a mass flow rate from a physical quantity proportional to the torsional displacement of the curved conduit around its axis of symmetry due to the Coriolis force acting on each curved conduit, the vibration of the flow tube is an additional mass that minimizes the excitation force to zero and is arranged parallel to the axis of symmetry of the curved conduit having a large natural frequency around the support axis of the curved conduit and the curved conduit or the curved conduit in parallel to the flow tube axis. A Coriolis force-type flowmeter is characterized in that it is fixed at the intersection with a bracket that supports a vibrating means, etc.
