Technique for measuring gas conversion factors

摘要

A method for determining hydrocarbon conversion factors for a flowmeter 17. A mixture of air, O2 and CxHy is burned and the partial pressure of O2 in the resulting gas is forced to equal the partial pressure of O2 in air. The flowrate of O2 flowing into the mixture is measured by flowmeter 13 and the flowrate of CxHy flowing into the mixture is measured by the flowmeter 17 conversion factor is to be determined. These measured values are used to calculate the conversion factor.
