AALBORG®'s GFC LOW COST self-contained ANALOG THERMAL MASS FLOW CONTROLLERS are designed to accurately measure and control the flowrates of gases. CONTROLLERS are constructed of rigid metallic components. Nylon is not used. Flowrates are unaffected by temperature and pressure variations.
Stainless steel models have wetted parts of stainless steel. Aluminum models have wetted parts of aluminum, brass and stainless steel. O-rings are VitonTM.
Local setpoint adjustments are conveniently accessible from the outside. External set point adjustments of the control valve are facilitated through a 15 pin D-connector. Control valves are normally closed proportionating electromagnetic valves.
A tiltable LCD readout is built into the top of the meter. Readings are in direct engineering units in terms of specific gases. Remote reading installations are possible by means of an optional extension wire supplied with a modular phone plug. Conveniently overlapping flow ranges.
