| titleOfInvention | Method for measuring flow rate and composition of gaseous isotope element mixture |
| abstract | PURPOSE:To make it possible to easily measure the flow rate and composition of a gaseous isotope element mixture in a real time, by connecting a calorimetric type flow meter and an orifice flow meter in series while connecting both of them to an operator and measuring the flow rate and composition of said gaseous mixture on the basis of a specific arithmetic expression. CONSTITUTION:A calorimetric flow meter 11 and an orifice flow meter 12 are connected in series and both of them are respectively connected to an operator 13. The process stream 10 of a gaseous hydrogen isotope mixture is successively supplied to both flow meters 11, 12 and the flow rate Q thereof is at first measured on the basis of the arithmetic expression Q=E/Cp.DELTAtheta(wherein Q is a flow rate, Cp is specific heat at constant pressure and DELTAtheta is definite temp. difference) imparted in the flow meter 11. Subsequently, the value of the flow rate Q is substituted for an arithmetic expression Q=(mC0epsilonpiD<2>/4)X(2gc.DELTAp/rho)<1/2> (wherein m is an opening ratio., C0 is counting of flow rate, epsilon is correction coefficient of expansion, D is pipe diameter difference before and after gas supply, gc is gravity conversion factor, DELTAp is pressure difference before and after gas supply and rho is gas density) to measure the composition of the gaseous mixture. |
