Abstract
A method for determining an energy content of a hydrogen-rich gas mixture using a gas density meter (101) is provided. The method includes the steps of providing a vibratory gas density meter (101) and meter electronics (112) with the gas density meter (101). The meter electronics (112) communicate with at least one external input (116). The meter electronics (112) are configured to measure a density of the hydrogen-rich gas mixture, measure a specific gravity of the hydrogen-rich gas mixture, and derive a calorific value of the hydrogen-rich gas mixture using the derived specific gravity and a plurality of constant values.
