SmartTrak 50 Mass Flow Controllers & Flow Meters

SmartTrak 50 Series digital gas flow meter & flow controllers by Sierra Instruments

Low cost Digital Mass Flow Controllers and Mass Flow Meters from Sierra Instruments

Sierra Instrument's SmartTrak 50 is a low-cost mass flow meter and flow controller that shares the same accuracy and repeatability as Sierra's flagship SmartTrak 100, it has a few less features and a slightly larger footprint - but at a more economical price. It is also ideal for lab researchers and systems integrators/OEMs.

The SmartTrak 50 series of flow meters and flow controllers are designed to deliver smooth, stable, accurate, and repeatable gas mass flow control that you can rely on every time. Like SmartTrak 100 it is unaffected by upstream gas temperature and pressure fluctuations, gas mass flow control is direct and unequivocal.

The SmartTrak 50 Series has a standard accuracy of +/- 1.5% of full scale. It's flexible and powerful direct-acting control valve sets it apart from the competition by minimizing leak-by, while offering a 300 ms response time to setpoint changes at +/- 0.25% repeatability.

Software: Free user software is provided with every unit.
