FMG FMR 300 & 600 Series Rotary Gas Flow Meters

The FMG FMR 300 & 600 Series rotary gas flow meters are built to meet demanding gas measurement requirements across utility, industrial, and compressed natural gas applications. Both meter series feature a modular cartridge design that enables efficient field servicing and cleaning, helping reduce downtime and maintenance costs.

The FMR 300 utilizes a lightweight aluminum body designed for high-pressure performance, while the FMR 600 incorporates a durable steel housing for even more demanding pressure environments. Advanced impeller and bearing designs improve resistance to pressure fluctuations, overload conditions, and long-term wear. [flowmetergroup.us]
