GFM / GFC Mass Flow Meters / Controller

GFM meters are economical, compact self-contained mass flow meters designed to read flow rates of gases with flow ranges from 10 mL/min to 1000 sL/min N2. Aluminum or stainless steel models with readout options of either engineering units (standard) or 0 to 100 percent displays are available. The mass flow meter includes an LCD readout built into the top of the transducer. This removable read out module is tiltable over 90 degrees to provide optimal reading comfort. Signal outputs (0-5 Vdc and 4-20 mA) are also obtainable.

GFC mass flow controller combines the features of a mass flow meter with a built-in electromagnetic valve that allows the flow-rate to be set to any desired flow rate within the range of a particular model. Setpoints are controlled either locally or remotely. The valve is normally closed as a safety feature to ensure that gas flow is shut off in case of a power outage.
