  • How Accurate is Your Monitor?

    When you consider the many regulations and guidelines that health and safety officers and first responders are faced with, it is amazing they maintain the ability to detect such a wide variety of hazardous pollutants and toxic agents.  There is no lack of regulations governing how to monitor chemical compounds, and the list grows longer all the time.  New standards for portable gas ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...

  • LFG engine protection for Viridor - Case Study

    Rapid changes in landfill gas quality can damage the engines it powers. To keep watch, Viridor has installed static automatic gas analysis and reporting equipment supplied by Geotech at its Whitehead landfill site near Manchester. Every ten seconds the equipment measures concentrations of CH4, CO2 and O2 and outputs the data in three, 4-20 mA channel signals. Control circuits receive the ...

  • Automatic calibration saves big

    Automatic gas sensor calibration technology was developed by Rel-Tek and proven over a decade of industrial applications involving large alternative fuel, transit bus garages.  CNG, LNG, LPG and hydrogen fuels present the possibility of explosive gas buildup indoors, so sustaining the accuracy of the installed gas monitoring system is a never-ending responsibility for the owner.  ...

  • Model 5100 Verification/Validation case study

    Background Many sensors used in gas analyzer systems come into direct contact with the process gas, and there is the potential for degradation over time especially with streams that contain contaminants like glycol, moderate to high levels of hydrogen sulfide etc. With sensor degradation, the analyzer response characteristics change resulting in inaccurate readings. In order to ...

  • Sonic nozzles for gas calibrators, when simplicity provides accuracy!

    Gas analyser’s calibration is a task required in many applications according to either legislation or quality systems management. This is the case for Air Pollution Monitoring or Continuous Emissions Monitoring devices installed in cabinets, for continuous analysis in remote locations. Measurements in traces range are performed and analytical devices specifications need to be validated and ...

  • Gas Monitor Bump Testing vs Calibration

    We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...

  • Maximising efficiency of AD plants with gas analysers - Case Study

    As focus around the globe is increasingly shifting towards renewable energy, anaerobic digestion (AD) has become an economically viable energy source that capitalizes on reusing our wasted materials. It is a relatively easy and natural means of turning a broad variety of complex waste into a simple fuel gas. It’s no surprise therefore, that the number of AD plants across the UK has risen in ...

  • New Developments in Thermal Dispersion Mass Flow Meters: In-The-Field Compensation for Changes in Natural Gas Composition

    Introduction The flow of natural gas in pipelines is often complicated by changes in the composition of the gas. The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. The method ...
