<P>PROBLEM TO BE SOLVED: To enable accurate measurement of flow rate of fluid even if the straight pipe portion of a flow channel is short while minimizing pressure loss of the fluid. <P>SOLUTION: This flow rate measuring device comprises a flow rate measuring part 3 provided in a duct 2 forming a fluid channel and a swivel flow generating part 4 provided in the duct 2 and upstream of the flow rate measuring part 3. The swivel flow generating part 4 generates swivel flow of the fluid in the duct 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
