Abstract
In this contribution a laser-based photometer detecting inelastic scattered light is presented capable of measuring the calorific value of natural gas and the H2 content in combination with an acoustic resonance analyzer to measure gas density. It is shown that the relevant parameters calorific value and gas density can be measured within several seconds with an uncertainty that is required for the gas turbine application using high hydrogen/ natural gas blends. A hydrogen-based economy shows us further applications for this exciting combination of gas sensing principles.
