Flow and Test solutions for those who demand precision.

Across Sierra's two divisions, flow measurement and automotive test, striving for the ultimate in accurate and repeatable measurement and control is the name of the game. In everything we do, we challenge the status quo and thrill in doing the “never before possible” to continually push our technologies and solutions to the next level. 

Recent examples of this motivation from our Flow Division are seen in our completely reinvented iSeries InnovaMass vortex and QuadraTherm thermal flow meters. Examples from our Automotive Test Division are the completion of a new F1 engine testing facility featuring complete design / build capability, advanced engine conditioning and fuel metering and conditioning capability.

Our mission is an uncompromising focus on quality, delivery, people, innovation and customer support.  We believe that by always staying true to our mission, we will build highly creative and productive relationships with our customers that endure.

Our Divisions:

Flow Measurement & Control Division
With more than 150 locations in over 50 countries, our Flow Measurement and Control Division is known for the design and manufacture of innovative high-performance fluid flow measurement and control instrumentation for nearly any gas, liquid and steam application spanning across global industries as diverse as scientific research, semiconductor, wastewater treatment, iron and steel, clean energy, aerospace and biotech to name a few.

Our Flow Measurement and Control Division designs and manufactures high precision capillary-sensor based Mass Flow Meters and Controllers for gas flow applications. We also design and manufacture Immersible Thermal Mass, Transit-Time Ultrasonic, Vortex Shedding and Multivariable flow instruments in both standard and customized versions for applications in industrial and hazardous environments.

Our technologies precisely measure and/or control very low flows of gas down to less than 1 sccm full scale as well as extremely high flows of gas, liquid, and steam. With rugged product design, cutting-edge innovation, and a worldwide team of flow experts, we know you will “Experience Our Passion for Flow.”

Automotive Test Systems Division
Driven by our long-established roots in engine emissions sampling systems, our acquisition of CP Engineering in late 2011 has significantly grown our Automotive Test Systems Division. We now cover the complete range of automotive test applications including engine, vehicle, powertrain, transmission, emissions, analytical and component testing.

Since the formation of our Emissions Division in the early 1990’s, we have been deeply involved in the engine and vehicle development and testing industry. Our innovative BG3 Partial Flow Dilution (PDF) engine particulate emissions sampling technology is the leading technology of its kind in the world and is viewed as the standard in the industry.

Our new Automotive Test Systems Division is now appropriately named, Sierra-CP Engineering. Sierra-CP is now the only US-owned complete turn-key automotive test systems company in the industry and has manufacturing and support facilities spread across the globe.

Mission, Vision

Our Vision: Experience Our Passion for Flow!

Our Mission: To be the leading manufacturer in the world of fluid flow and environmental flow measurement and control instrumentation in terms of: QD PICS (Quality, Delivery, Price, Innovation and Customer Support.)

Founded in 1971 by Dr. John G. Olin, Sierra has long been well known as a manufacturer of  high-performance fluid flow measurement and control instrumentation for use in numerous industries and applications throughout the world.  Adding to Sierra's expertise in fluid flow and systems integtration, Sierra founded its fast growing Environmental Flow group in 1991 which specializes in engine particulate emissions measurement and is known worldwide for its flagship partial flow sampling system called  BG-3 technology.  Sierra's two flow divisions, Fluid Flow and Environmental Flow, continue their leadership with a steady stream of innovative products that help customers meet tough flow challenges every day.

By combining superior product quality with a talented global support network of experts in over 150 locations in over 50 countries, Sierra works hard to consistently deliver quality flow measurement solutions and support to customers for the life of the product.

Our Thermal Mass, Transit-Time Ultrasonic, Vortex Shedding and Multivariable flow instruments are available in both standard and customized versions for applications in laboratory, industrial and hazardous environments. Sierra’s flow measurement technologies precisely measure or control very low flows of gas down to less than 1 sccm full scale as well as extremely high flows of gas, liquid, and steam. With rugged product design, cutting-edge innovation, and a worldwide team of flow experts: we hope you Experience Our Passion for Flow!

FEATURED PRODUCTS

FEATURED APPLICATIONS

Argon mass flow meters flow solutions

Thermal mass flowmeters and controllers are ideal for Argon application where precision is key. Sierra specializes in accurate mass flow measurement and/or control of Argon gas. Popular applications range from general industrial process control, inerting and steel purification processes to name a few.

Flow meters solutions for developing economies

Mass flow meters and mass flow controllers help developing countries explore their natural resources. Our thermal flow meters are widely used in flotation cells in mining. Our multivariable mass vortex flow meters are used in the oil and gas industry both at the wellhead and in the refinery. Thermal mass flow meters also have a place in the power generation industry where they are used to measure and control fuel-to-fuel air ratios.
