New microthermal technology for gas metering

Louise Smyth

New environmentally friendly technologies, such as power-to-gas and biogas production systems, will change requirements for the entire natural gas industry, including gas metering. Due to these trends, future gas metering will be confronted with new mixtures of natural gas, including those that contain significant amounts of non-conventional fuel gases such as hydrogen or carbon dioxide. These new gas mixtures present a challenge for all the technologies currently used in natural gas metering. Sensirion has been working on these issues for many years and is proud to announce a major breakthrough in microthermal gas metering using a new technology to measure thermal gas characteristics that was developed in-house.

Sensirion plans to commercialise this new technology by adding the new SGM6200 series to its current product portfolio of SGM6000 modules. Furthermore, the sensor company believes that the SGM6200 series fulfils both current and future market requirements. One single module covers natural gases in groups H and L and E (as defined in EN437) as well as natural gas mixtures, including non-conventional fuel gases with up to 25% hydrogen content. The SGM6200 family will output temperature-compensated volumes of natural gas, aligned with today’s most widely used billing systems for natural gas. Competitive prices and ultra-low current consumption below 10 µA enable Sensirion’s customers to design very competitive, cutting-edge meters for natural gas.
Currently, Sensirion plans to make samples available by February 25, 2018. Start of production for the G4 module of the SGM6200 family is planned for Q3 2018. By assessing additional physical properties of natural gas, the SGM6200 series paves the way for realising Sensirion’s vision of direct energy content monitoring of natural gas in gas meters.
