Title:
FLOW RATE MEASUREMENT DEVICE AND PIPING EQUIPMENT USING FLOW RATE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/031411
Kind Code:
A1
Abstract:
This fluid measurement device comprises a primary flow path that a fluid to be measured flows through, a flow rate measurement unit for measuring the flow rate of the fluid, and a secondary flow path that has fluid inlet and outlet ports in communication with the primary flow path and is disposed such that the fluid flows from the inlet port to the outlet port via the inside of the flow rate measurement unit. The flow rate measurement device additionally comprises an orifice part that is disposed in the primary flow path so as to be positioned between the inlet and outlet ports. The orifice part comprises an orifice part central flow path that includes a taper part where the flow path further upstream in the flow direction of the fluid has a wider diameter than the flow path further downstream in the flow direction and a plurality of orifice part side flow paths that are provided such that the openings thereof in communication with the downstream side are disposed on the inner wall of the orifice part central flow path.
