Industrial Gate Valves

Industrial valves are devices that are used to regulate liquids, gases, and slurries. The flow of liquids or gases can be controlled using these valves. This can be done through pipes and other passageways by opening, closing, and partially obstructing the passageway or pipe. Different types of Industrial Valves include: • Gate Valves • Globe Valves • Ball Valves • ...

Server Rack Blanking Panels - Why You Need Them

What is a Server Rack Blanking Panel A blanking panel is a piece of plastic or metal that fits into the empty spaces in your rack. Typically they come in 1U or 2U sizes, and they close off that U, only being removed when a new piece of equipment is to be installed. The fact that they will often times end up being removed means that many people question their need as they will be surplus to ...

Flow-induced errors in airborne in situ measurements of aerosols and clouds

Abstract. Aerosols and clouds affect atmospheric radiative processes and climate in many complex ways and still pose the largest uncertainty in current estimates of the Earth’s changing energy budget. Airborne in situ sensors such as the Cloud, Aerosol, and Precipitation Spectrometer (CAPS) or other optical spectrometers and optical array probes provide detailed information about the ...

No Need for Redundant Systems

How many gas monitoring systems does it take to measure a gas concentration? Strangely enough, the answer is not always one. Gas concentration monitoring is not always an easy task. In the ideal world, a monitoring system needs no maintenance, it is infinitely fail-safe, and it operates impeccable irrespectively of the conditions of the gas. However, then reality hits the system with more or less ...

Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

Micro Pulse LiDAR is an effective tool for monitoring and measuring dust and emissions produced by mining operations. Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining ...

Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

Fence-line Monitoring: Benzene and Beyond

Measurements of ambient air quality close to industrial facilities are sometimes referred to as fence-line monitoring, in particular if the ambition is to evaluate the facilities’ contributions to the air pollution situation. Fence-line monitoring can be of great importance and value in the vicinity of any potentially air-polluting industry, including oil and gas refineries, chemical ...

Micro Pulse LiDAR Monitors Air Quality at Mining Sites in Real Time - Case Study

Early Detection of Adverse Particulate Matter Aids Dust Management Dust emissions at open-cut coal mines are a potential threat to air quality in surrounding areas. To learn more about particulate matter (PM) and how it travels beyond a mine’s boundaries, a research grant from the Australian Coal Association Research Program (ACARP) was awarded to Pacific Environment, an environmental ...

Monitoring of Hydrogen Sulfide in Industrial Processes

Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

Selecting the Right Air Quality Monitor

There are many types of air quality monitors available, but which one is the best choice for measuring gaseous air pollutant concentrations? There are two classes of such air quality monitors: sampling monitors and in-situ monitors (“in-situ” = “in the original position”). Sampling monitors utilises a manifold through which the air to be analysed is pumped. A small air ...
