Density and concentration measurements are important in many applications in industries such as food & beverage, life sciences, oil & gas and chemicals to name a few. A density meter performs this measurement. This educational 4-minute YouTube video, Compact Density Meter Overview describes how density, temperature and concentration are directly measured. It explains the calibration […]
In many parts of the world, technologies to open shale formations for oil and gas production have yielded vast quantities of natural gas. The liquefaction process makes it practical to ship liquefied natural gas (LNG) across the globe. In a SmartBrief article, Emerson’s Buttler outlines the importance of calibration and measurement in growth of LNG […]
Yesterday, we looked at calibration of Coriolis mass flow meters in natural gas applications and mentioned piecewise linearization (PWL), but did not delve into it. Let’s do with today’s post. I found a presentation by Emerson’s Tonya Wyatt, Fine Tuning Coriolis Flow Meter Calibrations Utilizing Piece-Wise Linearization. The PWL calibration method basically looks at the […]
In this 27-minute YouTube presentation video, Custody Transfer Measurement and Calibration Round Robin Testing for Natural Gas with Coriolis Meter, Emerson’s Marc Buttler explains Coriolis meter calibration process and Piece Wise Linearization (PWL). His discussion includes Coriolis meter principles of operations, AGA Report No. 11— Measurement of Natural Gas by Coriolis Meter, conversion of mass […]
We often discuss aspects of some of the basic measurements in process control—flow, temperature, pressure, level, etc. Some other very important measurements in applications such as custody transfer, liquid interface detection, blending, separating, evaporating and product change—are density and viscosity—due to the changing composition of hydrocarbon liquids. In a whitepaper, Application of Density Meters to […]
