<p>The present invention relates to a method for measuring a gas flow by using a method for simply collecting a gas expansion coefficient and a run-off coefficient by calculating an insulation index, gas density, and a viscosity coefficient corresponding to each temperature and pressure condition after the insulation index, steam density, and the viscosity coefficient are calculated with a thermodynamic formula by a gas flow meter using a clamping device; a program thereof; and a flow measuring device. the present invention also supplies the flow measuring device characterized by more including a gas selection unit and a function selection unit in an information processing unit.
