Beside of many application possibilities this compact series GCM mainly target the classical applications of Rotameters.
Additionally to the advantages of the battery supply and of an integrated manual control valve these devices have a precise and clear to read LCD display, pressure independancy and intelligent control functions. So they are the modern solution for simple flow mesurement tasks. The devices are suiteable for line pressures up to 10 bar and measurement ranges from 20 Nml/min up to 200 Nl/min are available. Isolated 4-20 ma outputs for mass flow and temperature, optional relays, and a convenient RS232 and keypad user-interface, gives you the flexibility to integrate the functions of flow measurement with your specific needs. The Mass Flow Meter can be used on small dosing lines all the way up to large fuel gas feed lines.
FCI Mass Flow Meter can be used in aeration lines and flare gasses. Mass Flow Meter can be used with flow switches and level switches where they create superior

Mass Flow Systems
Complete Mass Flow Systems include Command Modules, transducers and cables.
Command modules contain appropriate power supplies, digital panel meters with 3-1/2“ digit LED readouts and
high precision potentiometers. External RS-232 or RS-485 are optional. Analog outputs are accessible through convenient
9 pin D-connectors. Sage Thermal Mass Flow Meters are designed for high performance mass flow measurement of flow rate and consumption of gases. such as air, oxygen, natural gas, nitrogen, digester gas, hydrogen, argon, carbon dioxide and other gases and gas mixes. They are field rangeable and have a convenient user interface. We have distinguished ourselves by offering a higher standard—our mass flow meter output is virtually independent of even large process temperature variations, and our digital electronics is impervious to external analog noise. In addition, we feature a back-lit display that reports mass flow, totalized mass flow and temperature.
