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.
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.
Oil wells almost always produce natural gas (“associated gas”) along with the petroleum. In many cases, it is uneconomical to process due to heavy contamination. As a consequence, this gas is combusted, “flared” or simply vented as-is during upset conditions in the process. Newly updated EPA regulations like 40 CFR Part 60 Subpart OOOO (also known as Quad O) as well as the new RSR MACT rule for refineries, requires oil & gas companies to report the flare gas emitted to our atmosphere....
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.

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.
Whether in foodstuff or pharmaceutical industry, in the chemistry or process engineering, metall processing or in automotive industry: in many branches of industry most different manufacturing processes require gas conditions with a pressure considerably below atmospheric pressure. A pressure of -700 mbar (300 mbar abs.) is considered as negative pressure. Below 300 mbar absolute the vacuum range begins, subdivided in rough, fine, high and ultra high vacuum.
The differences in compressor technologies can be found right where the demanding applications are. Where often highly critical processes gases and coolants are compressed. In the chemical, petrochemical, energy, food, or pharmaceutical industries. The demands on plant design, engineering, documentation and worldwide service in those industries are often just as high as the safety and environmental guidelines to be followed. For over 150 years, AERZEN has been developing a unique expertise for these industries....
Tekran offers the only completely integrated, automated system for measuring mercury speciation in air. The Tekran 2537, when coupled to the Model 1130 and Model 1135 provides a continuous record of gaseous elemental mercury, gaseous oxidized mercury and particle-bound mercury. Over the past 12 years, the Tekran 2537-1130-1135 system has been the most significant tool used to advance the understanding of the fate and transport of atmospheric mercury. See the Expert’s Corner for details about international...
Metal-working factories generate a lot of oily effluent as a result of manufacturing processes. The coolant emulsions tailored to the individual application contain oils, waxes, greases and preservatives, as well as a cocktail of ingredients to improve product properties. The emulsions used must not be discharged untreated into the drain system or open bodies of water; they must be disposed of at high cost.
The Tekran 2600 versatility is evident with the economical and convenient configuration for manual analysis of air samples collected on gold cartridges. Converting the instrument allows calibration by simple injection of gaseous Hg using the Tekran 2505. Once analyzed, the gold cartridges are immediately ready for redeployment.
Within the field of gas analysis much time is spent looking at the accuracy and uncertainty in the detection technique. However, without appropriate sample handling, what you are measuring could potentially bear little or no relation to your original sample.
CFCs are used in the manufacture of insecticides and herbicides and the environmental impact of their use must be well controlled. The treatment of CFC emissions to reduce the emissions in the intermediary steps of production needs to be monitored with 100% efficiency. Protea’s portable CFC analysers and continuous CFC monitoring systems can be configured with various sample inlets and analytical modelling to enable multi-samples to be measured on the one system. This means that both inlet and outlet to...
Current Total VOC MeasurementsThe most common, and current standard, method for measuring Total Volatile Organic Compounds (VOC) is the use of a Flamed Ionisation Detector (FID). This gives a representative value of the total carbon content of a gas stream, as the FID cannot tell which specific organic compounds are present.
CFC usage in industryAlthough the use of CFCs in domestic products has been widely phased out, CFCs chemicals still prove a vital ingredient in the production of insecticides and herbicides. Such products aim to increase the rate of crop production all over the world. All aspects of such a manufacturing process in relation to environmental impact must be well controlled. The use and pre-emission removal of CFCs in the intermediary steps of the insecticide production needs to be monitored with 100% efficiency.
