  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • Unmanned remote and wireless CDM monitoring case study

    Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

  • Saving waste in the boiler house

    Burner technology has improved greatly in recent years. Older Burners had a series of cams and levers that were calibrated to provide specific amounts of air for a particular rate of firing. Being mechanical items, these wore and sometimes required calibration. They, therefore, had to be regularly serviced and calibrated. Generally, new burners use frequency controlled motors and cams to open air ...

  • Monitoring Oil in Cooling Water

    The Situation A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid ...

  • Case study - rendering retrofit

    Challenge A prominent rendering facility in the southeastern United States was faced with loadings that were too high for the existing dissolved air flotation (DAF) unit. To minimize the amount of carry-over into their secondary system, they were forced to run at a very slow rate. Still, too many solids were being discharged from the existing DAF into the anaerobic pond. The ...
