The gasQS measuring equipment allows the measurement of heat conductivity, heat capacity and, by means of an additional flow measurement using a critical nozzle, the measurement of density. These physical sum parameters are used to reach conclusions about gas quality factors such as the air/gas ratio, the methane number, the Wobbe number or the calorific value.

No knowledge of the gas composition is required and it is fast, small and robust compared to common process chromatographs.

More information

Correlative measuring systems do not directly determine the output values, but use interrelations between two or several states or functions. However, these can be purely coincidental and must first be proved through causality, i.e. a directly connected cause and its effect. With our profound knowledge of the physical background, we ensure the direct connection. This knowledge allows us to simulate and determine the measurement performance without performing measurements, including in the case of new applications.

The innovative gasQS technology is intellectual property of Mems and has been an internationally legally protected trademark since 2014.
