Claims

[Scope of utility model registration request]

A vortex generator is provided in the fluid flow path, and the vortex generator guides a pressure change due to a Karman vortex generated in the fluid to a differential pressure chamber,
In a flow rate/flow rate detection device that reciprocates a movable plate in the differential pressure chamber and detects a signal by a pickup unit facing the movable plate to measure the flow rate/flow rate of fluid, the movable plate is sucked toward the pickup unit. A flow velocity/flow rate detection device comprising: a first magnet that attracts the movable plate in a direction that moves the movable plate away from the pickup portion; and a second magnet that attracts the movable plate in a direction that moves the movable plate away from the pickup unit.
