Claims

[Scope of utility model registration request]

A fluid measurement pipe, a bypass pipe arranged coaxially with the fluid measurement pipe in the fluid measurement pipe, an annular flow path formed between the bypass pipe and the fluid measurement pipe, and a support for the bypass pipe. In order to set the flow rate ratio of fluid between the impeller rotatable within the annular flow path, the annular flow path and the bypass piping to a predetermined value, the annular flow is introduced from the upstream side of the bypass piping. A flowmeter characterized by comprising an orifice plate for setting a flow division ratio in which a plurality of small holes penetrating the roadside are arranged in alignment.
