Litre Meter has announced the release of the Sierra Instruments Smart-Trak Series C100M digital mass flow controller (MFC) for larger gas flows. Smart-Trak offers end-users and OEM customers maximum flexibility, an easy-to-use interface, rugged stainless-steel construction, and true digital performance - now at flow rates up to 200 slpm! Smart-Trak demonstrates incredible quality and performance because it was designed so the physics are correct. This means a patented, inherently linear design with no curve fitting.

The result is a pure 1% accuracy and unsurpassed stability over the entire flow range, even in multiple gases.

The unique Dial-A-Gas feature and convenient Pilot Module interface easily change critical parameters in the field without sacrificing performance.

The Smart-Trak microprocessor is programmed for ten gases that are commonly used in biotech, pharmaceutical, analytical, and research applications.

Other gases may also be specified to create a custom instrument.

For remote monitoring and OEM applications, Smart-Trak also provides an RS232 output and a choice of four user-selectable analogue outputs.

Each Smart-Trak is scrutinised for a minimum of 2-weeks with our proprietary computerised characterisation process to assure every instrument is of the highest possible quality, will have no drift, and will remain in spec over the long-term.

The Smart-Trak small footprint permits easy drop-in replacement for any mass flow controller.

The original low flow size (for flow rates up to 50 slpm) is 3 x 1 x 5 inches while the new larger size (for flow rates up to 200 slpm) measures 4.5 x 1.5 x 6 inches.

The all-stainless steel instrument is custom-made for every application in any range from 0-10 sccm to 0-200 slpm full-scale.
