Sierra Instruments, Inc. products

Improve your filter sampling data by eliminating effects of dirty, wet or oily air on your results. Sierra`s air handling and scrubbing system is designed to clean compressor air before it enters a sampling system or analytical equipment within the test laboratory. The international standard for compressed air quality provides a simple system of classification for the three main contaminants present in any compressed air system: dirt, water and oil. We will work with you to specify the air quality class you require for a particular application and build a system to suit your needs.

Many customers supercharge their SmartTrak mass flow controller with the Compod upgrade! The innovative Compod mounts to the face of any SmartTrak to set up simple process control systems without the need for PLC’s or computers.

For lab researchers and systems integrators/OEMs, Sierra`s flagship SmartTrak thermal mass flow controller is a true multi-gas digital MFC designed to deliver smooth, stable, accurate, and repeatable gas mass flow control you can rely on, every time. Unaffected by upstream gas temperature and pressure fluctuations, gas mass flow control is direct and unequivocal.

For lab researchers and systems integrators/OEMs, the SmartTrak 50 is a true digital MFC and shares the same accuracy and repeatability as the flagship SmartTrak 100 with a few less features, slightly larger footprint, but more economical price.

The TopTrak 800 series provides an economical OEM gas mass flow meter in your choice of nylon, aluminum or stainless steel. Direct mass flow rate measurement with the nylon version at prices below that of a typical rotameter. Large tiltable display that can be mounted on the device or on a remote panel. Large cleanable sensor tube for use with dirty gases. Ask about OEM volume discounts on pricing to meet your budget requirements. For fast delivery, buy online and get next-day shipment.

Engineers in the Biopharmaceuticals industry require precise control of the gases used in bioreactors to optimize microbial growth and ensure proper mixing and distribution of the biomass. In addition, precision burner control is needed in order to produce the glass ampules, vials and bottles that are used to properly package the resulting biopharmaceuticals.

Rotameters, also known as Variable Area (VA) meters are used across nearly every industry where economical gas flow metering and flow regulation is required. Rotameters are what is known as a volumetric flow meter only capturing the gas flow volume, not gas mass flow rate. All volumetric flow meters and regulators are sensitive to gas pressure and temperature changes—a pressure change of just 1 Bar generates flow rate error of up to 50%.

BoilerTrak is designed to provide an economical, easy-to-install solution for precise natural gas measurement for heaters and boilers to increase efficiency. The instrument is also suited for compliance with new regulations for burning natural gas and propane in commercial boiler applications.

The FastFlo 620S is an insertion thermal mass air flow sensor designed to give you a highly reliable, responsive and affordable mass flow measurement for light industrial applications where a NEMA 4X (IP65) enclosure is acceptable.

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 first time rivals accuracies of Coriolis technology for measuring mass air flow rate and other gases.
