With regard to the quality and safety of drugs, authorities worldwide set high standards for the pharmaceutical industry. To ensure these high quality and safety standards, reliable instruments and methods are needed.
Precision high pressure mass flow control is very difficult. Sierra has met this challenge with a patented high pressure mass flow controller design that offers impermeable elastomers with very little leakby.
Our mass flow controllers in particular see extensive use in bioreactors, pill coating and the creation of artificial atmospheres for research. Our flow meters are used to leak test critical medical devices like stents, while our larger industrial devices are used to heat or steam-clean bioreactors and in facilities management in hospitals.
From heavy industrial to research and analytical applications, Sierra has a wide range of digital air flow meters and controllers with digital output protocols. Sierra offers digital gas flow meters and mass flow meters across two core technologies: Capillary Thermal, and Immersible Thermal.
The Series 8900 Acrylonitrile Analyzer provides direct measurement of Acrylonitrile in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits. The Series 8900 Acrylonitrile Analyzer employs a flame ionization detector (FID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is...
The BevAlert Model 8900 provides direct measurement of Vinyl Chloride, Acetaldehyde, Methanol, and Benzene (VCAMB) in Carbon Dioxide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor trace impurities in CO2 used in carbonated beverages.
Sierra specializes in accurate mass flow measurement and/or control of Nitorgen gas. One of the most commonly measured gases, applications are found across numerous industries ranging from general process control to scientific research and development.

Today’s food and beverages (F&B) are much more than just simple "organic fuels" needed for survival. Beyond their nutritive value, they are consumed for their taste or flavor. Increasingly, they are also a source for maintaining health and enhancing our well-being via high-quality nutrition. At the same time, with an ever-increasing number of processed foods, food quality and safety aspects are becoming more important. All the more because foods are highly complex materials – prone to degradation...

We get it. All fingers point at you if productivity slips because of incorrect steam flow calculation. All you really want are flow instruments that are easy to install and provide highly accurate data. And work 24/7 with no downtime. Meet the original. In the ’90s, Sierra was the first multivariable mass vortex flow meter supplier in the world when we pioneered InnovaMass. Vortex volumetric flow and multivariable mass flow meters are the ideal technology for calculating steam flow. Our InnovaMass vortex...
Pneumatic transport of bulk materials, quickly, gently, and with minimal energy expenditure – a job for real specialists. Oil-free rotary lobe hybrid blowers, rotary lobe compressors and screw compressors from AERZEN can handle any kind of transport need. With unparalleled efficiency and reliability.
Thermal mass flowmeters are ideal for Carbon Dioxide metering and mass flow control. Sierra specializes in accurate mass flow measurement and/or control of CO2 gas. Applications range from general industrial process control across numerous industries to Green House Gas monitoring requirements and general research.
Voltammetric determination of many heavy metals is also possible in municipal or industrial wastewater. On account of the usually high organic load the sample is usually mineralized by means of UV digestion.
As an innovative steam flow meter manufacturer, Sierra’s InnovaMass brand was the first multivariable mass vortex flow meter to launch to market in the late 1990s. Today our flow meter steam technology is successfully used across numerous applications. Sierra`s multivariable product line features an in-line version, the InnovaMass 240 vortex flow meter; a unique immersible version, the InnovaMass 241; and the InnovaMass cryogenic version.
We have developed many flow meters and controllers to measure the emissions from landfills and other green house gas producers, in addition to being a long standing leader in the testing of emissions for large engines. Water treatment is also an important driver for the company as we continue to develop innovative solutions for waste water treatment.
Sierra’s offers a complete line of precision flow solutions for any gas, liquid or steam measurement to improve energy efficiency in all facilities management applications. Our mass vortex meters are used to allocate steam, our in line thermal mass flow meters track and allocate natural gas and compressed air usage, and our clamp-on and insertion ultrasonic meters provide accurate water and water-based fluid measurement.
Determination of the pH value provides information about the acid or base action of the soil solution. This in turn is enormously important for the nutrient supply and microbial activity of the soil. For example, many metals (trace elements) are considerably more mobile in acidic soils. If the soil pH values are very low, toxic levels can soon be reached and these can damage the roots of plants. On the other hand, excessively high pH values quickly lead to a shortage of trace elements because of immobilization.
