The battery powered in-line flow meters have been used for process monitor and metrology, especially where explosive gases such as natural gases are of interests. MF-GD series utility gas mass flow meters were first introduced in 2009 and the current version is the 3rd generation of the company’s MEMS utility gas meters designed for city natural gas metering. The current upgrades include automatic gas recognition, a new mechanical design with a flanged connection, better power management, and enhanced long-term reliability. The products are also deployed for control and improvement of burner efficiency using natural gases. MF-GD covers most of the models for commercial city gas metering applications.
