14 AIRMONITORING
New data analytics application helps industry tackle emissions, making the shift towards predictive maintenance Increased governmental and societal focus on emissions mean that industry is under ever greater pressure to increase the
agility and reliability of emissions monitoring in real-time. ABB’s Datalyzer is designed to help customers respond to this challenge. The comprehensive, cloud-based modular application provides real-time status across a fl eet of analysers and plants. In doing so, it lowers ownership cost and reduces capital expenditure.
Datalyzer collects data from emissions monitoring analysers which is then routed to an on-site Edge device (Micro PC). The Edge device sends the relevant information up to Datalyzer which sits in the Microsoft Azure cloud. The application analyses the data received transforming it into a concrete information for decision-making.
The end user receives the information from Datalyzer across three different dashboard views. The fi rst shows the fl eet view, the second the plant view and the third a more detailed analyser view. This combination provides both an ‘at a glance’ vision of the overall emission monitoring equipment status alongside valuable detailed asset parameters. Heatmaps of the installed base, historical trends and systems diagnostics are amongst the key parameters provided.
A new approach and highly innovative solution to reliable and accurate gas dilution
Dilution is effectively all about fl ow ratio: to ensure maximum accuracy, selecting nozzles or calculating the linearity correcting polynomial coeffi cients, fl ows must be measured. The most common problem with diluters is that in high ratios the fl ow of the gas to be diluted and the fl ow of the diluting gas are very different to each other. Therefore, measuring the smallest fl ow with the same meter used for the highest fl ow results in very low resolution and therefore inaccurate dilutions. Using different meters creates different chain tracing errors which is even worse.
With Be.T.A. Strumentazione’s BetaCAP series of precision diluters, different fl ows are obtained by grouping in parallel a different number of equal capillaries. The capillaries are measured one by one with high resolution and the fl ow of the groups is not measured but calculated by adding the individual capillary fl ows. The relative accuracy of the sum is considerably better than the accuracy of fl ow measurement on the single capillary.
To provide an electronic pressure control across capillaries Be.T.A. Strumentazione use pressure meters. In comparison to fl ow meters they have a lot of advantages in term of stability, linearity and reliability. However, the main advantage of electronic pressure control comes from knowing and using the physics of capillaries setting calculated set-points to adjust pressure, differential pressure and viscosity relationships. Traditionally, when capillaries or critical nozzles are used the diluter operates “step by step”, individual capillaries or nozzles combinations give individual dilution ratios.
MFCs diluters are based upon linear fl ow control, dilutions are linearly changing in a continuous dilution range.
The BetaCAP product uses discrete components (capillaries) to produce a continuous dilution range. Capillary combinations give the dilution steps, and those steps are moved by changing the pressures applied to capillaries complying with their physical laws.
To calculate the viscosity of a gas mixture many empirical formulas are available in which the physical parameters of the components must be placed: one of them is the component viscosity, that we may fi nd in literature tables (each fl uid chemical component has a viscosity)
This calculation is one of the more widely used, because it solves many problems both in fl uid dynamic and in medicine (blood circulation) and it therefore enables accurate results.
Other technologies (MFCs) are infl uenced by the calorifi c power of the fl uid, as well as by the heat transfer coeffi cient and other factors such as the design of the fl ow measuring sensor.
The BetaCAP is built by manifold, using two solid blocks and constructing all the pneumatic circuit by crossing holes within the solid. This construction creates a very compact and highly rugged unit that is isothermal, with low leakage levels and minimal dead volumes.

Datalyzer also offers QAL-3 assessment* and reporting, as well as event-based notifi cations by e-mail. Live analyser process data together with value added insights and reports are amongst the application’s key features. Historical trends are tracked for up to fi ve years, uncovering recurring patterns in the equipment performance and providing the platform for predictive maintenance. Adherence to cyber security standards prevent unauthorised access while ensuring data integrity.
Continuous gas analysers such as ABB’s ACF5000 and ACF-NT analysers are compatible with Datalyzer with extensions planned to include Advanced Optima and Easy Line in the fi rst quarter of 2022.
Datalyzer forms a part of the ABB Ability™ Genix Industrial Analytics and AI suite. The platform provides data analytics and industrial AI applications as the next generation operational intelligence and insight.
New cost-effective
sampling console Apex Instruments has launched Peak32 Top Tier Technology, an advanced, multi-functional metering console series powered by the PIC-32 microcontroller module and featuring a backlit sunlight-readable display. Peak 32 consoles are built to be rugged, compact, and cost-effective. The XD-502 Gen 2 is the latest release in the series currently in production.

The Apex Instruments Peak32 metering console series revolutionises console displays by combining backlighting and sunlight readability, two features that are seldom found together in the same display. The compact PIC-32 microcontroller acts as a central processor that accepts multi-sensory data and incorporates data logging capabilities. Previously, different functions within the console would be performed by multiple discrete units. By removing separate individual components, Peak32 provides up to 50% savings depending on the unit. The consolidation also allows for more convenient maintenance. Apex Instruments incorporates protection into the PIC-32 module to help it survive harsh testing environments.
