  • Thermal Mass Flow Meters

    With more than 40 years of experience developing and selling inline and insertion thermal flow meter technology, Sierra has established a large and successful installed base. Our immersible thermal gas mass flow meters were also deemed North America's #1 selling immersible thermal mass flow meter (2009 Flow Research, Yoder). We offer both inline and insertion thermal mass flow meters for heavy and light industrial applications. Our thermal flow meters range from our highest-performance Quadr

  • Sierra QuadraTherm™ - Model 640i - Air / Gas Thermal Insertion Mass Flow Meters

    Sierra QuadraTherm™ - Model 640i - Air / Gas Thermal Insertion Mass Flow Meters

    The QuadraTherm® 640i is the most accurate insertion-probe thermal mass flow meter for air / gas mass flow rate measurement on the market today, achieving gas mass flow rate accuracy never before possible, +/- 0.75% of reading above 50% of full scale. The QuadraTherm 640i air / gas mass flow meter marks an accuracy breakthrough in thermal dispersion technology achieving extreme precision with 'percent of reading' accuracy, which for the...

  • Sierra QuadraTherm - Model 780i - Inline Thermal Mass Flow Meter

    Sierra QuadraTherm - Model 780i - Inline Thermal Mass Flow Meter

    The QuadraTherm 780i is the most accurate inline thermal mass flow meter for air / gas mass flow rate measurement on the market today, achieving gas mass flow rate accuracy never before possible, +/- 0.5% of reading above 50% of full scale. The QuadraTherm rivals accuracies of Coriolis technology for measuring gas mass flow rate with a breakthrough thermal dispersion technology achieving “percent of reading” accuracy.

  • Sierra SteelMass - Model 640S - Insertion Gas Mass Flow Meter

    Sierra SteelMass - Model 640S - Insertion Gas Mass Flow Meter

    Named North America's #1 selling thermal mass flow meter (2009 Flow Research, Boston MA), Sierra’s SteelMass Model 640S delivers precise measurements for heavy-duty industrial gas mass and air flow meter measurement applications. This insertion thermal mass air/gas flow meter offers precision SCFM (standard cubic feet per minute), SFPM (surface feet per minute) and SMPS (standard meters per...

  • Sierra qMix™ - Field-Update for Gas Composition Changes

    Sierra qMix™ - Field-Update for Gas Composition Changes

    qMix is a powerful, user-customizable gas mix feature included with every QuadraTherm thermal mass flow meter as a free beta trial version. qMix provides the ultimate gas flow measurement field flexibility by allowing you to create custom gases or gas mixtures to compensate for gas compositional changes in the field.

  • Sierra FlatTrak™ - Model 780S - Inline Thermal Mass Flow Meters with Flow Conditioning

    Sierra FlatTrak™ - Model 780S - Inline Thermal Mass Flow Meters with Flow Conditioning

    North America's #1 selling inline thermal mass flow meter (2009 Flow Research, Boston MA) delivers precise measurements with heavy-duty industrial gas mass and air flow meter measurement applications.  Choose from a wide variety of inline and insertion thermal mass air flow meters for precision CFM (cubic feet per minute) measurement of gas mass flow rate in industrial environments.

  • Sierra MultiTrak™ - Model 670S - Multi-Point Gas Mass Flow Meters for Large Ducts and Stacks

    Sierra MultiTrak™ - Model 670S - Multi-Point Gas Mass Flow Meters for Large Ducts and Stacks

    The 670S dynamically compensates for changes in the flow profile by using up to four independent mass flow sensing points to measure the instantaneous average gas mass flow velocity. The 670S is commonly used in petrochemical refining, coal-fired electric power generation, steel manufacturing and many other industrial processes that face the challenge of accurate and repeatable gas mass flow measurement in very large pipes or ducts.

  • Sierra ChlorineTrak™ - Model 760S - Chlorine Gas Mass Flow Meters

    Sierra ChlorineTrak™ - Model 760S - Chlorine Gas Mass Flow Meters

    The ChlorineTrak 760S has been specifically designed to perform as an accurate and cost-effective mass flow measurement solution for chlorine injection processes found in typical waste-water treatment applications. Given the corrosive nature of chlorine gas (particularly in the presence of moisture), extremely expensive Hastelloy was needed for main flow body construction.  And this drove the cost up thousands.  Finding a...
