  • Advances in Thermal Dispersion Mass Flow Meters - Part 1 Principle of Operation

    Abstract This paper describes an advanced microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and has a dry velocity sensor that uses no potting materials instead of the traditional potted velocity sensor. This unique new mass flow meter automatically manages changes in gas selection, ...

  • Tech Note: Flare Gas Measurement Innovation; Retain Flow Metering Accuracy Even if Gas Composition Changes

    It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also ...

  • Core technology part 3: thermal--multivariable mass vortex

    In 1997, Sierra Instruments took proven vortex shedding technology to the next level with the launch of the Innova-Mass® Model 240 & Model 241 Multivariable Mass Vortex Flow Meter. Sierra was the first to offer this unique solution for measuring the mass flow of gases, liquids and steam. Vortex shedding flow meters have been in use for many years. The typical device is a flanged in-line ...

  • Reducing Costs of Steam Flow Measurement

    Traditionally, steam flow has been measured with a differential pressure device. This is typically an orifice plate. However, such devices are inherently volumetric flow measurements. As we have discussed in previous blog posts, changes in pressure and temperature ...

  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Portable IR analyzers: the ideal measurement solution for biofuels blend quality and wastewater testing

    Two challenges facing the biofuels industry involve compliance with blend quality standards and wastewater regulations. According to a study done by the National Renewable Energy Laboratory, 1 the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For ...

  • Biofuels blend measurements with portable mid-infrared analyzers

    Globally, governments are putting more emphasis on sustainable energy sources and are creating energy policies that promote the production and use of biofuels. With the Renewable Fuels Standard-2 (RFS-2), the United States set biofuels blending volumes to 12.95 billion gallons (49.0 billion liters) for 2010, increasing to 36 billion gallons (136 billion liters) by 2022. With similar mandates or ...

  • Remote controlled `Pit Hog™` dredge removing sludge from aeration lagoons at Los Alisos, California, Waste Water Treatment Plant

    The Los Alisos Water District Water Reclamation Plant is removing raw sewage solids, decayed algae and microorganisms, and algae-laden sludge from its aeration lagoons using a Liquid Waste Technology (LWT) remote controlled lagoon dredging system. The tertiary wastewater treatment plant treats four million gallons per day. Officials of the Lake Forest, California facility initiated the buildup ...

  • Taking matters into hand - Case Study

    Biofuels must be up to scratch as contaminated or improperly blended fuel can damage a  company’s bottom line. To ensure product quality several options exist including laboratory analysis, field test kits and portable lab instruments.  Laboratory testing would be the ideal solution if everyone had the budget and the time to wait for the results.  But in a market where time ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • Vibrating feeders for stockpiling and reclaim

    The expanding applications of vibratory feeders for controlling the flow of bulk materials, and their adaptation for processing requirements, have developed considerable interest in stockpiling and reclaim systems. The general design of these units consists of a material transporting trough, or platform, driven by a vibratory force system. The flexibility and variety of designs is limited only by ...
