Absolute Ozone®


Low Cost GFM Mass Flow Meter

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.


Steel Mass Flow Meter - Model 822S and Model 824S

Economical Analog Stainless Steel Mass Flow Meters

The Model 822S and Model 824Sare 316 stainless steel versions of our popular Model 822 and Model 824 economical nylon MFM’s. Our Model 822S and Model 824Sare a favourite among customers who want cost-effective mass flow measurement but must have stainless steel construction.  Both models are ideal for measurement of most clean dry gases including mixtures, toxics, corrosives, and combustibles.


In addition, both models offer standard 0-5 VDC or 4-20mA output signals. The Model 822S is equipped with a tiltable LCD display that can be mounted on the device or on a remote panel. The Model 824S is a compact OEM configuration that comes without the display.


The Model 822S and Model 824S are available in your choice of engineering units and in any flow range from 0-10 sccm to 0-500 slpm. Both models use Sierra’s patented sensor design with access ports to facilitate easy sensor cleaning.  In addition, Sierra’s Platinum Sensor Technology eliminates zero-drift and creates excellent long-term reliability.
