While the Emerson Exchange 365 global user community has a very vibrant forum for DeltaV distributed control system (DCS) users, there is also some great knowledge sharing happening in many of the other areas such as the Measurement Instrumentation, Valves, Actuators & Regulators, and other discussion forums in the Control & Safety Systems groups to […]
What is the perfect flowmeter? Emerson’s Tonya Wyatt references an earlier Flow Control magazine article, to open her article, Flowmeter Diagnostics Optimize Production in Process Plants. It: …never drifts or wears. It never needs zeroing. It measures in mass units. It is immune to the effects of changing fluid properties and fluid dynamics, density, viscosity, […]
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 […]
If you are new to the world of process safety, you quickly learn that it has its own jargon with phrases such as safety instrumented functions, proof test intervals, PDFavg, etc. A Flow Control magazine article, Ensuring safety compliance with optimized proof testing, written by Emerson’s Afton Coleman, Erik Mathiason and Tonya Wyatt does a […]
At the Emerson Exchange conference in Austin, Emerson’s Afton Coleman, Erik Mathiason and Tonya Wyatt presented, Improve Safety Proof Test Capabilities with Intelligent Instrumentation. Their abstract: Safety Instrumented Systems are designed to be the most critical line of defense against a catastrophic failure. Ensuring that each component of the system is working properly is required, […]
