Smart -Trak® 2 is the next generation of Sierra’s flagship Model 100. Building upon the unprecedented performance, user-friendliness and flexibility end-users have come to expect with the original Smart-Trak, Smart Trak 2 gives users the world’s most linear sensor, smoother valve performance, more robust electronics and even more control over a wide range of functions. The result is a series of mass flow meters and controllers that demonstrates premium flow instrumentation doesn’t have to be difficult to use.
Smart -Trak 2 is designed so that the physics are correct. Excellent performance results from a patented, inherently linear Laminar Flow Element (LFE) design, advanced platinum sensor technology, and Sierra’s proprietary frictionless-hovering control valve.
Smart-Trak 2 is available with an innovative and user-friendly Pilot Module, a front-mounted or hand-held control device that allows users to “Dial-A-Gas®”, change flow rate, modify engineering units or re-configure the instrument. With the Pilot Module, the user can set zero, span and full scale for each of 10 different gases independently to accommodate unexpected application or system design changes.
With the addition of Sierra’s Compod, Smart Trak 2 transforms into a fully network-enabled MODBUS RTU device. Just like the award-winning original, Smart-Trak 2 delivers performance, flexibility and value.
The result of over five years of your feedback, our next generation flow meter gives you unprecedented control, independence and flexibility.
We have advanced the science of our direct-acting control/shut-off valve by using proprietary Frictionless-Hovering Technology, allowing you to smoothly control gas mass flow over a wide range of temperature and pressure
Now, you can adjust calibration in the field for any of the 10 pre-programmed Dial-A-Gas gases independently. The user-friendly Pilot module (mounted or hand-held) lets you view and change a wide variety of critical control functions.
Add Sierra’s new Compod and Smart Trak 2 becomes a truly intelligent flow controller that simplifies flow control installations and expands networking capabilities.
Smart-Trak 2 features Dial-A-Gas® technology for true digital performance in up to ten pre-programmed gases with the same unit (gas type list can be programmed on request). Another unique factor of the Model 100 is the pilot module which replaces expensive control/readout electronics and is available mounted to the face of the instrument or in a convenient hand-held version.
At Sierra, we are confident that our Model 100 mass flow meter will pass your most demanding tests, delivering the accuracy you need whether you monitor the flow of air or other common gasses. Whether you are making your first mass flow meter purchase or replacing an older thermal meter, the charts below will help you decide which type of Smart-Trak 2 is the right fit for your needs.

Buying Time In Suspended Animation For Dr. David Kraus, the linearity and precision of the Smart-Trak® Model 100 matters. Imagine being suspended in time—having your metabolism slow, heart rate decrease, and temperature drop. This is what Dr. Kraus and other scientists are discovering—with small amounts of H2S, we can buy time in suspended animation. Read Complete Story.
