Claims

[Scope of utility model registration request]

A vortex flowmeter that measures flow velocity or flow rate by detecting the alternating force acting on a force-receiving body by a Karman vortex includes a pipe through which a measurement fluid flows, a support mechanism provided on the pipe wall of the pipe, and the support. an insertion hole provided in the tube wall of the conduit facing the mechanism; and an insertion hole inserted into the conduit through the insertion hole, one end of which is removably attached to the support mechanism, and the other end fixed to the insertion hole. a columnar force-receiving body, a recess provided in the axial direction of the force-receiving body; and a recess provided in the recess symmetrical to the axis of the force-receiving body and facing in a direction perpendicular to the flow, and pressed and fixed to detect the force-receiving body; at least two stress detectors whose signals are processed differentially with respect to each other;
A vortex flowmeter characterized in that the support mechanism is configured to always support the force receiving body at an upstream point in the direction of the drag force.
