Claims

[Scope of utility model registration request]

(1) In a flow rate measuring device that includes a flow velocity rectangular flow rate detector and a variable throttle valve for adjusting the cross-sectional area of the flow path installed at a flow rate measurement position of a flow path pipe, the variable throttle valve controls the amount of fluid passing through the flow rate detector. A flow rate measuring device characterized by having a plurality of valve bodies that operate according to flow velocity in a high flow rate region and a low flow rate region.

(2) Flow rate measurement according to claim 1 of the utility model registration claim, characterized in that the valve body for a high flow rate region and the valve body for a low flow rate region are interlocked with each other with a certain time difference or opening degree difference. Device.

(3) The flow rate measuring device according to claim 1 or 2, wherein each valve body is arranged in series or in parallel with the flow pipe.

(4) Claims 1 to 3 of the utility model registration claim characterized in that at least one of the valve bodies is disposed within a small cross-sectional area flow path formed by a partition wall. The flow rate measuring device according to any one of the above.

(5) The flow rate measuring device according to any one of claims 1 to 4, wherein the flow rate detector comprises a plurality of flow rate sensors arranged correspondingly to each valve body.

(6) Flow rate measurement according to any one of claims 1 and 4, characterized in that one flow rate detector is disposed at a position where a flow velocity in a low flow rate region can be obtained. Device.
