Microthermal mass flow meters for G4 and G6 smart gas meters

July 08, 2015 // By Graham Prophet
Sensirion (Staefa, Switzerland) has added two versions of its SGM70xx mass flow meter modules for G4 and G6 gas meters. These microthermal gas meter modules enable real-time gas flow monitoring and offer high-level reliability and long-term stability.

Onboard software in the mass flow meters guarantees precise gas quality compensation. Microthermal gas flow modules from Sensirion have been available for G1.6 and G2.5 gas meters. These latest modules for the G4 and G6 gas meters offer resistance to dust and dirt as well as reliability, and long-term stability. They feature a standard connection and an I ²C interface. The compact design permits easy integration into gas meters. The mass flow meters are digital, temperature compensated, pressure corrected and completely calibrated for gas and natural gas. SGM70xx comes with software and hardware approved by the GWI (Gas and Heating Institute) to compensate for different types of gas mix. If required, the gas meter module is also supplied with European NMI component certification.

SGM70xx mass flow meters from Sensirion have been used for several years in gas meters for industrial and residential environments. Over 100,000 such microthermal mass flow meters have already been installed in Italy and Germany. Sensirion is currently the only company able to offer its customers a complete design-in solution. This means that everything comes from a single source. In addition to calibrated gas meter modules, Sensirion also delivers an electronic reference design that simplifies integration of the necessary hardware and software and also makes NMI part certification available.

The SGM70xx mass flow meter allows users to monitor the flow and consumption of gas reliably and in real time. For end-users, it boosts transparency and convenience and allows them to optimize their energy consumption.
