Measuring method for gas flow rate
专利汇可以提供Measuring method for gas flow rate专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the responsiveness of a sensor and to apply the sensor even to a high-temperature gas flow by calculating the flow rate of gas to be measured from the 1st and the 2nd electromotive force values according to an Nernst's equation.
CONSTITUTION: A prescribed pump current Ip is fed between the external pump electrode 18 and internal pump electrode 22 of an oxygen pump cell 4 from a DC power source 30 to causes the oxygen in the object gas flowing in a gas passage 10 to vary in concentration, and a potentiometer 34 detects an electromotive force E
2 based upon the oxygen concentration difference between the object gas and reference gas (atmosphere). Further, a potentiometer 32 detects an electromotive force E
1 based upon the oxygen concentration difference between the oxygen concentration in the object gas before being pumped by the oxygen pump cell 4 and the reference gas. Then, the flow rate of the object gas is calculated from the electromotive forces E
1 and E
2 according to the equation (R: gas constant, T: absolute temperature, (n): atomic number, F: Faraday constant, Po
2 (1): partial pressure of oxygen in reference gas, Po
2 (1): oxygen distribution in object gas, and K
1 : 2.303×R/nF).
