The present invention makes it possible to easily obtain a compressibility factor that is a characteristic of a fluid, and thereby dramatically improves the accuracy of flow rate measurement by an ROR system or the like. The invention is adapted to include: a chamber having a constant volume; a flow rate controller connected to the chamber so as to make it possible to introduce or lead a fluid into or out of the chamber at a constant flow rate; and an information processor adapted to calculate a compressibility factor depending on the pressure of the fluid on the basis of time changes in pressure inside the chamber when the fluid is introduced into the chamber at the same flow rate as each other through the flow rate controller under two different pressure conditions inside the chamber.
