| Abstract | PROBLEM TO BE SOLVED: To enlarge a flow rate measurement area by using a plurality of channels. SOLUTION: A fluid entering from a flow-in passage 1 passes through an open opening/closing means 4, and the flow rate is measured by a measuring means 5. The opening/closing means 4 and the measuring means 5 are controlled by a control means 6. A plurality of channels attain a high flow rate, when they are completely opened; large flow rate can be measured; and the case of a small flow rate can be coped with by opening only one channel. In this manner, the flow rate which ranges from a minute flow rate to a large flow can be measured speedily and accurately, by increasing or reducing the number of channels.
