Thermal-mass technology is a proven means for measuring the flow of gasses and liquids. The recent technological advances and miniaturization have enabled the use of the technology for high-volume, cost-sensitive applications such as natural gas metering. Two studies published in 2021 now also confirm the long-term reliability of this technology for applications in harsh environments. The studies investigated thermal-mass gas meters following operation in the field for up to over 10 years. They concluded that all meters were operating well within the accuracy limits prescribed during service and that the majority of meters still fulfilled the requirements for brand-new gas meters. Coupled with the release of a dedicated European standard in 2021 (EN 17526), thermal gas technology is therefore a cost-effective, proven and reliable solution for gas metering that is already powering millions of gas meters worldwide. Additionally, it offers extensive self- and network-diagnostic capabilities and is ready for a wide range of natural gas compositions including hydrogen blends and pure hydrogen.

In this article, we’ll take a look at the different classes of refrigerants used in the HVACR industry, current shifts in their usage, and some of the leak detection technologies which may be essential in enabling the industry to comply with new environmental and safety regulations. When ozone-depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were phased out in response to the Montreal Protocol, hydrofluorocarbons (HFCs) were introduced to replace them.1 However, HFCs are potent greenhouse gases, and worldwide efforts are currently underway to reduce their usage.

In this article, we will examine the metrological behavior of the microthermal measurement principle for gas meters operating with natural gas mixtures containing significant amounts of hydrogen. We will present measurement data, discuss measurement accuracy and operational safety, and explain why the compact size of microthermal gas meters can be maintained regardless of the hydrogen admixtures, which is a key advantage compared to other meter Technologies.

Every year 7 million people die worldwide as a result of exposure to polluted air. With up to 5 times more air pollution being found indoors than outdoors, indoor air quality is currently one of the top five environmental risks to public health as it can impact people’s energy efficiency, performance, well-being, and health. One aspect that negatively affects indoor air quality is carbon dioxide (CO2)...

When we think of “air quality”, we tend to think of air pollution in the regions surrounding our homes. We rely on measures such as the Air Quality Index to let us know when airborne pollutants in our towns or cities reach levels that may cause or exacerbate health issues. When summer humidity brings an increased risk for asthma sufferers or when dangerous smog accumulates in cities, the message is simple: to protect your health, stay indoors.

How will we be living in the future? This is a question that humanity has always yearned and worked to answer. Finding out the answer, surprisingly, is not limited to time travel. Humanity has a tendency to shape its own future by pushing forward certain developments, and now, at the forefront of this decade’s developments are autonomous deliveries, smart home devices like thermostats that control heating, cooling and ventilation based on user preferences, refrigerators that automatically send out orders when food is running low, and smart speakers that communicate with their owners...

Particulate Matter, abbreviated as ‘PM’, is a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. PM includes particles with different characteristics – i.e. shape, optical properties, size and composition ¬– but it is most commonly divided into sub-categories based on the particle size information. Different PM categories are usually reported under the ...

Modern medicine has been able to drastically improve the quality of life of the global population. Diseases such as polio, syphilis, tuberculosis or the plague have been almost eradicated and are successfully treatable or curable. The next milestone for modern medicine is personalized medicine. This novel discipline does not target the broad population, but focuses on the individual for the diagnosis and beyond ...
