Dual-gas metering system and method

A gas metering device, comprising:

• a metrology unit;
• a sound-speed measuring device;
• a memory device;
• and
• a processor, in communication with the metrology unit, the sound-speed measuring device, and the memory device, wherein the processor is configured to execute statements defined on the memory device to perform actions comprising:
• receiving a flow of a dual-gas, wherein the gas metering device is downstream from a hydrogen injection site;
• receiving a first speed of sound within gas upstream from the hydrogen injection site;
• measuring a second speed of sound within the dual-gas;
• calculating a ratio of the first speed of sound and the second speed of sound;
• and
• calculating a hydrogen gas concentration based at least in part on the first ratio.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, configure a computing device to perform actions comprising:

• receiving, by operation of a gas meter, a flow of a dual-gas, wherein the gas meter is downstream from a hydrogen injection site;
• receiving, by operation of the gas meter, a first speed of sound within gas upstream from the hydrogen injection site;
• measuring, by operation of the gas meter, a second speed of sound within the dual-gas;
• calculating, by operation of the gas meter, a ratio of the first speed of sound and the second speed of sound;
• and
• calculating, by operation of the gas meter, a hydrogen gas concentration at the gas meter based at least in part on the ratio.
