SmartTrak 100 Mass Flow Controllers & Flow Meters

Smarttrak 100 Flow Meter & Flow Controller from Sierra Instruments

Premium Digital Mass Flow Controllers and Mass Flow Meters from Sierra Instruments

The SmartTrak 100 series from Sierra Instruments is ideal for use in lab research and systems integrators/OEMs applications. This flagship range of SmartTrak 100 thermal mass flow controllersr are a true multi-gas digital MFC delivering smooth, stable, accurate, and repeatable gas mass flow control that you can rely on. It is unaffected by upstream gas temperatures and pressure fluctuations, making gas mass flow control with Sierra’s SmartTrak 100 unequivocal.

Availablility in any flow range specified up to 1000 slpm and higher. The SmartTrak is CE approved and comes in various sizes with industrial waterproof enclosures, operating pressures,temperatures, and industry form factors.

Pilot Module: With the remote or face mounted pilot module display/interface, view and change every aspect of SmartTrak at any time with the push of a button. Simply choose a gas from the menu and it’s ready to go, without losing any accuracy. You can also adjust engineering units, flow range, and set zero, span and full scale independently for each gas.

Quality Calibration: SmartTrak’s NIST traceable accuracy is backed by Sierra's ten point, primary standard calibration over the entire flow range.  SmartTrak has a strong and flexible control valve with accessible PID valve tuning to assure best speed and reliability. Custom valve orifice sizing yields full-range stability. If you need something special, Sierra is able to customise, often free of charge.

DIY Calibration: You can calibrate your own mass flow meters and controllers in-house, all necessary software and training and even the flow calibration standards required for the job. 

Software & Digital Communications: Free user software and a variety of communications protocols like Modbus, Profibus and Foundation Fieldbus, make every SmartTrak easy to integrate into your digital communications network.

The Thermal Advantage: Thermal mass flow technology is an industry standard for mass flow control of gases because it measures flow directly, at the molecular level. In essence, counting and controlling every gas molecule flowing through the instrument to achieve unmatched precision.

Accuracy and application flexibility result from:

  • Thermal mass flow technology provides direct mass flow
  • A patented, inherently linear Laminar Flow Element (LFE) design
  • Advanced platinum-wound capillary sensor technology
  • Proprietary frictionless, hovering control valve
