Premium Digital Mass Flow Controllers and Mass Flow Meters

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 our 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 customizes often free of charge.

DIY Calibration: If you prefer to calibrate your own digital flow meters and mass controllers in-house, Sierra provides 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.

Special Pricing: We work with you to meet budget requirements and cost targets.  Ask about OEM volume discounts.

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

Rule-of-Four Calibration: The ONLY Guarantee of Accuracy!

At Sierra, we have a saying:  “Instrument accuracy is only as good as its calibration.”

Sierra is one of few manufacturers today that perform a detailed 10-point calibration across the entire mass flow range. We strictly adhere to using primary standards and the NIST “rule of four.” This means our gas flow primary standards are required to be four times more accurate than the device under test.

This “rule of four” is Sierra’s calibration bedrock and absolutely essential for the quality you demand.  When researching your next MFC, ask about calibration.

Application Flexibility

If corrosive, toxic, or reactive gases are a concern, the SmartTrak 100 is compatible with corrosive gases. Free user software and communications protocols like Modbus, make every SmartTrak easy to integrate into your digital communications network.
 

User's Guide

Download our FREE user's guide to MFC's.  This white paper describes capillary tube mass flow meters and mass controllers best practices for use in general purpose industrial and laboratory applications and in the fabrication of semiconductor devices.   It provides a detailed description of the major components-- -flow body, flow conditioner, bypass, capillary sensor tube, control valve, and electronics. Flow ranges and specifications for which this technology is best suited are presented. The paper explains the principle of operation; describes gas conversion factors that provide multi-gas capability in a single instrument; lists best practices for users, including the selection, installation, and operation of the instruments; and concludes with a discussion of preferred methods of flow calibration.
