Claims

[Scope of utility model registration request]

A flow meter body whose inside is a flow path for the fluid to be measured, an impeller provided in the flow path and rotated by the fluid, and a position in the flow path that is outside the position facing the impeller. It consists of a partition wall that is movable based on the differential pressure between the front and rear walls, and an adjustment member that is displaced according to the movement of the partition wall and changes the area number of the passage that guides the fluid to be measured to the impeller. A grooved turbine meter in which the area of the passage increases as the flow rate increases, and the area of the passage decreases as the flow rate of the fluid to be measured decreases.
