    Principles of Operation:
    Metered 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.  Two 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.  Output signals of 0 to 5Vdc and 4 to 20mA are generated indicating mass molecular based flow rates of the metered gas.  Flow rates are unaffected by temperature and pressure variations within stated limitations. 

    General Description:
    Compact, self contained GFM mass flow meters are designed to read 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.  The mechanical layout of the design includes an LCD readout built into the top of the transducer. This readout module is tiltable over 90 degrees to provide optimal reading comfort. It is connected to the transducer by a standard modular plug, and is also readily removable for remote reading installations.

    Transducers without LCD readout are offered for OEM applications.  GFM mass flow meters are available with flow ranges from 10 mL/min to 1000 sL/min N2. Gases are connected by means of 1/4” 3/8” 1/2” compression fittings and 3/4” FNPT fittings. Optional fittings are available.  These meters may be used as bench top units or mounted by means of screws in the base.  Transducer power supply ports are fuse and polarity protected.
