Single probe point measurement (or limited path length)

One cross-duct monitoring path in the plane with the highest skewness


Comments Flow profile unlikely to change


Flow profile is expected to change with flow rate


Flow profile is expected to change considerably with flow rate


A skewed flow profile, possibly due to swirl, i.e., the point in the profile with the maximum flow rate is rotating and the best way to secure a representative average is to monitor in a cross or across two chords


The Source Testing Association (STA)


The Source Testing Association (STA) was established in 1995. Its membership comprises representation from process operators, regulators, equipment suppliers and test laboratories. The STA is a non-profit making organisation. The STA is committed to the advancement of the science and practice of emission monitoring and to develop and maintain a high quality of service to customers. Its aims and objectives are to: • Contribute to the development of industry standards, codes, safety procedures and operating principles • Encourage the personal and professional development of practicing source testers and students • Maintain a body of current sampling knowledge • Assist in maintenance of a high level of ethical conduct • Seek co-operative endeavours with other professional organisations, institutions and regulatory bodies, nationally and internationally, that are engaged in source emissions testing The Association’s headquarters is based in Hitchin, Hertfordshire, with meeting rooms, library and administration offices. The Association offers a package of benefits to its members that includes: • Technical advice relating to emission monitoring • Conference and exhibition opportunities • Seminars and training on a variety of related activities • Representation on National, European and International standards organisations • Training in relation to many aspects of emission monitoring • Liaison with regulators, UK and International, many of whom are members

However, the standard provides a framework for improving the quality of flue gas flow rate monitoring for emissions reporting and other purposes.


In March 2017 a technical report was published PD CEN/TR 17078:2017 Guidance on the application of EN ISO 16911-1


The Technical Report does not follow the numbering of EN ISO 16911-1:2013; however for easier handling it uses the same headings and sub-headings as EN ISO 16911-1:2013. It does not repeat text, tables or diagrams from EN ISO 16911-1:2013, instead it refers to the relevant sections of the Standard.


It is therefore essential that the user has a copy of the Standard to refer to. For sections of the Standard where this Technical Report does not provide any text or guidance it is deemed that the relevant section does not require any additional clarification.


World’s first solar-powered air quality monitoring station


ENVEA has inaugurated in July the world’s premiere solar powered criteria pollution monitoring station in its headquarters in Poissy, France (Paris region). The Solar AQMS is an all-in-one and self-sufficient air quality monitoring station that can be installed anywhere, even in isolated locations. Able to withstand high temperatures without air conditioning and without connection to the electricity grid, it operates 24 hours a day, 7 days a week, powered solely by solar energy. This pilot monitoring station contains the well-known eco-designed e-Series analysers. Certified QAL 1 and US-EPA approved, they offer the best metrological performance for continuous monitoring of CO, O3


, NO2 , SO2 , and fine particles PM10 / PM2.5.


Eco-designed, this new series of gas and particle analysers with very low energy consumption, have been recently enhanced to withstand high ambient temperature variations and support 24 V power supply. Thanks to these unique features, the analysers can endure temperatures up to 50-55°C without air conditioning.


In addition to these advanced technologies, the Solar AQMS station is equipped with e-SAM and XR©, ENVEA’s data acquisition and handling systems. They feature centralised data management in the cloud for processing, analysis and reporting, threshold alerts, as well as remote energy management and station control (calibration, diagnostics, etc.).


This innovation represents an important breakthrough for governments and institutions worldwide struggling to set up supportive measures and regulations to curb air pollution. It will support the air quality measurement across the developing world struggling with the reliability of their energy supply, as well as the

forward-thinking ‘smart cities’ looking to re-define their energy mix and supporting renewables on the grid. The very low energy consumption of such a station, its ease of integration into the urban or rural landscape and advanced connectivity and proactive interactivity with operators, are making it perfectly suited for remote areas as well as for smart-cities.


Today, more than 20,000 traditional pollution measurement stations connected to an electricity grid are located around the world. For example, the upgrading of the 670 measuring stations spread over France would save some 20,000 kWh/day, the equivalent of the annual consumption of nearly 1,500 households.
