  • Axetris Sensor Field Test

    The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

  • Determination of Flow Rates in part-filled Applications using the Radar Method

    Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for ...

  • The quality of the measurements in the environmental field

    Over recent years in various ways errors in environmental measurements have been criticised and large amounts of money wasted. It therefore becomes ever more necessary to increase the culture of the rigorous experimental measurement and handling of data. This is particularly important in fields such as our environment and our cultural heritage so closely connected to our life and our ...

  • Field verification of on-line hydrocarbon dew point measurements

    Introduction The Michell Condumax II applies a fundamental measurement principle for direct measurement of hydrocarbon dew point. Measurement performance is assured through comprehensive factory test and calibration, to verify that each analyzer offers accurate determination of the temperature at which hydrocarbon condensate forms. Further extensive examination confirms highly sensitive ...


  • Comparison of different measurement methods of odour and odorants used in the odour impact assessment of wastewater treatment plants in Poland

    The aim of this study was to compare sensory and analytical methods used to measure odour and odorants concentrations for odour impact assessment on municipal wastewater treatment plants (WWTPs). A range of sources and odour or odorants concentrations were used to compare the methods. Four different odours and odorants measurement methods were compared: field olfactometry using Nasal Ranger® ...

  • Leveling the carbon playing field

    Climate change is one of the most far-reaching economic challenges of our times. Unchecked, it threatens the welfare of people around the globe. Mitigating the worst of its impacts will require mobilizing capital and technology in innovative ways that will transform the global economy. The good news is that if we do it right we can generate technologies and markets that will not only leave us a ...

  • Random fields in SVSlope and SVFlux

    Geotechnical engineering, as a general practice, has always struggled with quantifying the significant amount of variability that can be present at any given site. There may be variability present in field sampling methods, equipment, lab testing procedures, level of training of field personnel, or many other such factors. One particular problematic aspect of slope stability analysis is the ...


  • Microstickies agglomeration by electric field

    Microstickies deposits on both paper machine and paper products when it agglomerates under step change in ionic strength, pH, temperature and chemical additives. These stickies increase the down time of the paper mill and decrease the quality of paper. The key property of microstickies is its smaller size, which leads to low removal efficiency and difficulties in measurement. Thus the increase ...

  • Free-field calibration in China

    Practically all reference microphone calibrations that are performed by national metrology institutes are pressure response calibrations. This is the case even if most practical measurements are carried out under free- or diffuse-field conditions. Fortunately, for measurement microphones, there are essentially fixed ratios between the pressure-, free- and diffuse-field responses. Therefore, the ...

  • ClarityNet® Improves Field Training

    Virginia Department of Environmental Services, Arlington, VA 'I like the way online training measures an employee's retention span and understanding of the programs,' says Dennis Cuddy, Safety Specialist. Employees also like the 24/7 access. 'The employees like going on the computer because it's more convenient for them to fit safety training into their work schedules,' he adds. ...

  • The soldier salesman: field instrumentation

    “The victorious strategist only seeks battle after the victory has been won, whereas he who is destined for defeat first fights and afterwards looks for victory.” — Sun Tzu, The Art of War These words may apply to warfare, and though they were written over two thousand years ago by a Chinese general, they could not be more accurate than when applied to today’s sales ...

  • Dynamic coupling of near field and far field models for simulating effluent discharges

    In many cases, (processed) wastewater or thermal effluents are discharged into the marine environment, rivers or lakes. To accurately determine the dispersion, recirculation and environmental impacts of outfall plumes, it is important to be able to model the different characteristics of the outfall plume in detail – from the near field (metres around the outfall) to the far field (up to ...

  • Successful Dunbar Field Life Extension

    The advent of high-power multiphase pumps is changing the world of oil production. In particular, they allow continued production from fields that are nearing the end of their useful lives. These revolutionary pumps have been in operation since autumn 1999 on the Dunbar platform, in the UK sector of the North Sea. Multiphase pumping (MPP) is essentially a means of adding energy to the ...
