Abstract
A flow volume measurement device for a turbo compressor includes a first pressure guide tube communicating with an intake pipe connected to a second compression stage having a compressor impeller that compresses a gas; and a second pressure guide tube communicating with an intake port of the second compression stage, which has a smaller internal diameter than an internal diameter of the intake pipe, and measures the flow volume of the gas on the basis of a difference in pressure between the first pressure guide tube and the second pressure guide tube.
