Abstract
A dual-gas metering system and method is described herein, wherein percentages of two types of gas in a gas flow are determined. The system uses two speed of sound measurements, and calculates a percentage of hydrogen gas within a mixture of natural gas and hydrogen gas. In a further example, a first speed of sound within a single type of gas (e.g., natural gas) is obtained. This measurement may be obtained from a remote device operating in a region of the gas system upstream of a location wherein a second type of gas (e.g., hydrogen gas) is introduced. A second speed of sound within a dual-gas mixture is measured. A hydrogen concentration value is calculated based at least in part on the first speed of sound and the second speed of sound, such as by using a ratio of the two speeds of sound and a lookup table.
