The enhanced model GFM is a low cost
self-contained Thermal Mass Flowmeter, designed to accurately measure the
flowrates of gases. 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. A nine pin AD connector is included
to facilitate 0 - 5 Vdc and 4 - 20 mA analog outputs. Flowrates are
unaffected by temperature and pressure variations. Aluminum and stainless
steel models are offered. Zero and span adjustments are conveniently
accessible from the outside, a dip switch is added for external adjustment
of decimal point of the LCD readout.
