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!
