Each of these controllers incorporates an advanced \"U\"-shape tube sensor in conjunction with flow passage elements constructed of aluminum and brass for non-corrosive gases or 316 stainless steel for corrosive applications. Zero and span adjustments are accessible from the outside of transmitters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrinciples of Operation\u003c\/strong\u003e\u003cbr\u003eMetered gases are divided into two laminar flow paths, one through the primary flow conduit, and the other through a capillary sensor tube. Both flow conduits are designed to ensure laminar flows and therefore the ratio of their flow rates is constant.\u003c\/p\u003e\n\u003cp\u003eTwo precision temperature sensing windings on the sensor tube are heated, and when flow takes place, gas carries heat from the upstream to the downstream windings. The resultant temperature differential is proportional to the change in resistance of the sensor windings. A Wheatstone bridge design is used to monitor the temperature dependent resistance gradient on the sensor windings which is linearly proportional to the instantaneous rate of flow.\u003c\/p\u003e\n\u003cp\u003eOutput signals of 0 to 5Vdc and 4 to 20mA are generated indicating mass molecular based flow rates of the metered gas.\u003c\/p\u003e\n\u003cp\u003eThe combined gas streams flow through a proportionating electromagnetic valve with an appropriately selected orifice. The closed loop control circuit continuously monitors the mass flow output and maintains it at the set flow rate.\u003c\/p\u003e\n\u003cp\u003eFlow rates are unaffected by temperature and pressure variations within stated limitations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeneral Description\u003c\/strong\u003e\u003cbr\u003eCompact, self contained GFC mass flow controllers are designed to indicate and control flow rates of gases. The rugged design coupled with instrumentation grade accuracy provides versatile and economical means of flow control. Aluminum or stainless steel models with readout options of either engineering units (standard) or 0 to 100 percent displays are available.\u003c\/p\u003e\n\u003cp\u003eThe built-in electromagnetic valve allows the flow to be set to any desired flow rate within the range of the particular model. The valve is normally closed as a safety feature to ensure that gas flow is shut off in case of a power outage. Setpoints are controlled either locally or remotely.\u003c\/p\u003e\n\u003cp\u003eThe LCD readout built into the top of the transducer is tilt able over 90 degrees to provide optimal reading comfort. It is connected to the transducer by a standard modular plug, and is readily removable for remote reading installations. Transducers without LCD readout are offered for OEM applications.\u003c\/p\u003e\n\u003cp\u003eGFC mass flow controllers are available with flow ranges from 10 sccm to 1000 sL\/min N2. Gases are connected by means of 1\/4” compression fittings and Optional fittings are available. These controllers may be used as benchtop units or mounted by means of screws in the base.\u003c\/p\u003e\n\u003cp\u003eTransducer power supply ports are fuze and polarity protected.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLeak Integrity\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003e1 x 10\u003c\/span\u003e\u003csup\u003e-9\u003c\/sup\u003e\u003cspan\u003e smL\/sec of helium maximum to the outside environment.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eIncluded Components:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGFC17A-VAL6-A0: \u003c\/strong\u003eThermal Mass-Flow Controller Aluminum Viton-A Seals 1\/4\" Compression Fitting LCD Display Na \/ 0 - 5 Vdc\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3NC-10-SS: \u003c\/strong\u003eNitrogen N2 0 - 10 Standard L\/Min Standard Metering Pressure (14.7 Psia) Standard Temperature (21.1°C \/ 70°F)\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e± 1% FS accuracy is standard\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRigid metallic construction\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAvailable flow ranges starting from 0 to 10 sccm up to 0 to 1000 slpm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaximum pressure of 1000 psig (70 bars)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLeak integrity 1 x 10-9 sccs of helium\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNIST traceable certification\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBuilt-in tilt able LCD readout (some models)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLocal or remote setpoint control\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e0-5 Vdc and 4-20 mA signals\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCircuit protection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTotalizer option\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDownload Documents\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/en_Aalborg_EM20250925_GFC.pdf?v=1775556071\"\u003eModel GFC thermal mass flow controller catalog page\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/A_GFC_Manual_TD9709M_Rev_X.pdf?v=1775623093\"\u003eGFC Operating Manual, Rev.
