> City gas mass flow metering > LPG metering for cylinders or pipeline > Other gases applicable The MF-GD series utility gas mass flow meters were first released in 2009, and the current version is the third generation, designed for city natural gas metering. It includes automatic gas recognition, a new mechanical design with a flanged connection, better power management, and enhanced long-term reliability. The products are also deployed to control and improve burner efficiency using natural gas. MF-GD covers most models for commercial city gas metering applications that are approved for hazardous zones.
