LISST-SL velocity thresholds
Is there a low velocity threshold for the LISST-SL? Does it need a minimum flow speed in order to sample? What is that? Absolutely! The internal pump in the SL will adjust the intake velocity to match the ambient flow speed in order to make the sample intake isokinetic. However, it is necessary to maintain a minimum pump velocity in order to avoid settling of particles inside the instrument. This ...

Not all differential pressure meters are created equal
Due to the dynamics of liquids and gases flowing through elbows, valves, pumps, and other pipeline structures, every flow-meter methodology has its own design limitations. Unlike Venturi meters, pitot tubes, orifice plates, and other devices, V-Cone meters provide highly accurate and reliable readings with minimal straight-pipe length restrictions and virtually no maintenance, in pipe sizes up to ...

How To Make a Fan Performance Curve
Fan Curve Development for Centrifugal Fan Applications The fan performance curve shows the pressure and flow rate that the fan will produce for any system connected to it. The actual fan performance is dependent upon the detail design of each system. System designers calculate process air requirements, and the fan application engineer selects fans to meet those requirements, which are ...

Experiences from a round Robin test for flue gas temperature, volume and flow measurements
ABSTRACT In Flanders, laboratories, recognised for emission measurements in the framework of the environmental legislation (Vlarem II), have to implement a quality system that meets the requirements of EN 45001 and are forced to participate in external quality controls organised by AMINAL, the Flemish Administration for environment and/or the reference laboratory for air measurements, e.g. Vito ...

Oil Sampling Best Practices
Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These access sampling points make it easier for operators to quickly and easily ...

New LFG Collection System Utilizes QED’s Revolutionary LFG Measurement and Control Technology - Case Study
“The main advantage, to me, is the Fine Tune™ Control Valve* that is used on the QED wellhead - it’s one of those revolutionary things in the landfill gas industry. Gate valves don’t give you very good control unless you always want the valve 100% open and you can apply as much vacuum as possible. But when it comes to low-flow wells then it’s important to be able to ...

Better combustion airflow monitoring at the Hunan Yiyang power plant
China has experienced tremendous growth in electricity demand over the past two decades. Coal-fired plant construction has exploded in the country to meet its seemingly insatiable appetite for electricity. Because most power plants in China use coal as fuel, it is imperative that new coal-fired plants be as clean and efficient as possible. This demand for cleaner plants has led to new and ...

Accuracy In Adversity
It is a fact of the industry that oil and gas companies are required, by various rules and regulations, to routinely perform gas sampling to establish gas composition, flow rates and gas properties. In order to comply with regulations, gas sampling tools must achieve high accuracy at low flows with varying gas compositions, temperatures and pressures. For many technologies, these requirements can ...

Increase biogas production, aeration basin efficiency with the right flow meter
In our competitive economic climate, many plant operators have a mandate to tune their plant’s performance by efficiently using biogas in cogeneration processes and increasing aeration basin efficiency, both of which can save thousands of dollars in the critical secondary stages of wastewater treatment. In many cases, these facilities are retrofitting with new flow measurement ...

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 ...
