Sierra's flagship Smart-Trak^® digital mass flow meters and controllers are now available in 1000 slpm high flow versions. From very low flows (down to 0.1 sccm) to high flows (1000 slpm), Smart-Trak^® demonstrates that premium flow instruments do not have to be hard to use. This combination of convenience with un-matched performance and flexibility has earned the 100 Series awards and praise as one of the finest Mass Flow Controller's in the world.

The Smart-Trak^® High Flow is designed so the physics are correct! Excellent accuracy and repeatability coupled with unsurpassed instrument stability result from a patented, inherently linear design, advanced platinum sensor technology, and a valve that is strong, flexible and forgiving. Sierra's 100 Series family of instruments has raised the bar and set a higher standard in the Performance MFC marketplace.

Every Smart-Trak^® instrument features Dial-A-Gas^® Multiple Gas capability so that one unit may be used with up to 10 gases. Smart-Trak^® is constructed entirely from 316 Stainless Steel, so it can be used with any clean gas including toxics, corrosives, combustibles and mixtures.

The unique Pilot Module replaces expensive control/readout boxes and is available mounted to the face of the instrument or in a convenient hand-held remote version. The pilot module allows these control functions—gas type, setpoint value, setpoint source, engineering units, output signal, valve state (open, closed or automatic), full scale value, and password. These features are also available from your computer via RS-232. You may also choose from 4 different analog signals.

The Smart-Trak^® High Flow instrument is custom-made for every application in any range from 0-100 slpm to 0-1000 slpm full-scale.
