COMBINED FLOWMETER

摘要

PROBLEM TO BE SOLVED: To make accurate flow measurements by performing very effectively the operation of straightening the flow of a fluid in a flow passage. SOLUTION: In this combined flowmeter A in which a flow sensor 2 is disposed in the flow passage 4 of a fluidic flowmeter 1, flow-straightening nets 6a-6c and a flow-straightening grid 7 are disposed in the flow passage 4. The flow of a fluid is thereby processed into a generally uniform distribution of flow velocities by the flow straightening nets 6a-6c and further into two-dimensional flow by the flow-straightening grid 7. Therefore the operation of straightening the flow of the fluid in the flow passage 4 is performed very effectively and accurate flow measurements can be made.
