Precise measurement of natural gas requires high accuracy, low pressure drop and direct mass flow reading—all the hallmarks of Sierra’s immersible thermal, mass vortex and thermal mass flow controllers. Our mass flow controllers are ideal for natural gas flow measurement with 100:1 turndown and no moving parts, providing a robust MFC solution. Our natural gas flow measurement instruments can also handle liquefied natural gas (LNG) via our cryogenic mass vortex meters.
For over 40 years Sierra has advanced our flow technology to offer customers around the globe the most cutting-edge thermal technology on the market. From heavy industrial to research and analytical applications, Sierra has a wide range of digital air flow meters and controllers with digital output protocols for easy network integration. Sierra offers digital gas flow meters and mass flow meters across two core technologies: Capillary Thermal, and Immersible Thermal. Buy a large selection our air flow meter...
Environics gas mixing, blending and dilution systems provide for precise mixing of gases for a wide variety of clinical applications. Our systems can produce gas concentrations from percent to ppb levels for single or multi-point calibration. The high accuracy of our mixers make them the units of choice for a wide variety of laboratory and research applications. For example, Environics Biological Atmosphere Incubation Mixers provide stable and accurate gas mixes for any laboratory or clinical need. You can...
More and more food packaging companies are utilizing Modified Atmosphere Packaging (MAP) or Equilibrium Modified Atmosphere Packaging (EMAP) to preserve the shelf life and/or appearance of their packed food. At Environics, we know it is essential that your MAP/EMAP gases be consistent and accurate in order to guarantee the desired quality in the end products.
Gas Chromatography requires a stable repeatable flow of the carrier gas with negligible temperature drift. The Axetris MFC provides excellent control of the gas flow resulting in sharp peaks and high resolution of the chromatograms. Multiple calibrations allow the control of Helium, Hydrogen or Nitrogen. Due to the high turn down ratio of 1000:1 and more, a broad range of flows can be controlled.
With its high turndown and direct mass flow, our immersible thermal meters are the instrument of choice for measuring aeration basin air flow and monitoring digester gas. Our multivariable vortex meters are used to measure steam in the cogeneration processes, while our ultrasonic flowmetersare used for influent and effluent measurement.
A safe laboratory environment requires an
effective method for clearing toxic material from fume hoods. Since all handling of toxic
materials is completed in these hoods, it is
critical to have a procedure to evaluate their
operation to assure adequate protection for
laboratory workers. The InfraRan Specific
Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood
efficiency in accordance with ASHRAE and
other standards. Manufacturers identify the flow
dynamics (factors that...
Bioreactors and fermentors are used in a variety of biotechnology and industrial applications, e.g. in cell culture or microbiology experiments. A precise control of gas flow is essential for controlling the biological process and to achieve the desired result.
With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to...
