MONITORING & METERING


blocks the light of a certain wavelength,meaning only the required wavelengths make it past the filter to reach a detector. This detector measures the intensity (or attenuation) of the IR light, which can determine the precise concentration of gas that may be present. Different filters allow different wavelengths of light to reach the detector, which can, in turn, be used to detect other gases and distinct particles. As it works using the unique properties of light,


this kind of sensing technology offers near- limitless scope. It can analyse the particulate matter in human breath, allowing for a detailed breakdown of the particles that enter and leave our lungs with every breath we take. At the other end of the scale, it can be installed in satellites and sent into orbit tomonitor for significant global gas leaks. While both of these applications require very different systems in size and scope, the principle behind the technology is the same. Newer gas analyser instruments use a laser diode


mounted on a thermo-electric cooler to tune a laser’s wavelength to the specific absorption wavelength of a particular molecule. They exploit their high-frequency resolution, which results in enhanced sensitivity – more significant levels of interaction between gas molecules and light in the order of parts per billion – and discrimination, as they are tuned to specific gas compounds. This eliminates the potential for false alarms, a common headache with other commonly used gas detection technologies. And, by incorporating different filters into a system that allow different wavelengths of


light to reach the detector, it is possible to check for multiple other gases using the same compact design. This allows for monitoring almost any harmful gas, from methane to carbon dioxide to radon.


KNOWLEDGE IS POWER The benefits of these sensors include fast response times and accurate results without using any additional gases to operate. This technology has advanced to detectors that continuously monitor for combustible gases and vapours within the lower explosive limit and provide alarm indications. These can be deployed within oxygen-deficient or enriched areas, requirelittlecalibration, and are immune to sensor poison, contamination, or corrosion. This technology is notmerely for preventing

Withmanufacturing industries on the verge of a data-driven revolution, this data sharing will enable manufacturers to establish a carbon emissions baseline and provide the foundation for initiatives to decarbonise production operations. This can then be used to promote our most powerful ally in the quest for a safer future – education. Granular data on air quality – at a

Energy has always been an industry in transition – managing volatility, advancing technology, and innovation to power the world’s progress and economic development, is simply what it does. That role has never beenmore important than it is right now.
