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.

Founded in 1971 by Dr. John G. Olin, venture within Sierra and experience our passion for innovation and precision measurement and control. It was Dr. Olin’s dream that Sierra be built on innovation, creative opportunity, entrepreneurial spirit, and team camaraderie. We are proud to continue those traditions today. Discover our culture – a family-owned, open atmosphere for interaction that emphasizes individuality, respect, growth, and strong customer relationships.

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.

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!

Designing and Building Complex, Custom, Integrated Facilities

Engine and vehicle test cells are complex systems. A strong development plan starts with:

  • A suitable physical space and location
  • Clear understanding of the exact data that must be delivered on an accurate and repeatable basis

From mechanical layout, controls and software to dynamometers and peripheral equipment, Sierra CP can handle every facet of your project with a combination of process knowledge, subject matter expertise and integration experience that makes our services uniquely valuable.

Carefully thought out engine or vehicle movement and linkage with integrated custom test cell equipment is important from a test and data quality standpoint, as well as the efficient operation, maintenance, and future flexibility of the test facility.

Our In-Cell Equipment Advantage

We are truly unique in that we own the vast majority of our technology IP ranging from test automation software and hardware to engine conditioning, fuel metering, emissions and analytical equipment.  In many cases, our customers are pushing the edge of innovation with their engine or vehicle R&D.  Since we own all of our equipment, change is easy and cost effective. We regularly improve, innovate, resize or upgrade our test equipment as well as our CADET automation software to meet changing customer needs.

Typical Project Scope

Sierra CP offers comprehensive in-house design, fabrication, integration, commissioning, preventative and ongoing maintenance and support services. Our highly trained specialty groups work to ensure every project aspect runs smoothly.  We monitor and managing every aspect of each project scope, such as:
