Level Blog: Remote Proof Testing Safety Level Switches

One of the necessities in managing safety instrumented systems throughout the IEC 61511 safety lifecycle is to perform periodic proof tests on the components in a safety instrumented function to verify proper function. A short 2:44 YouTube video, How to Remotely Proof-Test the Rosemount 2140:SIS shows how this proof testing can be performed remotely for safety level switches to save time & costs and reduce risk. ...

DeltaV Blog: Applying Embedded Model Predictive Control

James Beall The history of model predictive control (MPC) dates back to the early 1970s invented at Shell Oil and was known as Dynamic Matrix Control . MPC was designed at that time to solve largescale control challenges. As technology advanced, this technology could be more widely applied on smaller-scale challenges. At this past 2019 AIChE Spring Meeting , Emerson’s James Beall presented Unique Applications for...

Valves Blog: Avoid Operational Issues with Proper Control Valve Selection

Because they directly touch the process flow, control valves play a significant role in the stability, robustness and variability in the process. One bad-acting control valve can create large problems for safe and reliable operations. James Beall At last week’s AIChE Spring Meeting , Emerson’s James Beall presented Specifying Control Valve Performance to Achieve Desired Process Performance. In his comprehensive presentation...

Level Blog: LNG Storage Tank Radar Level Measurement

Liquefied natural gas is methane with some ethane possibly mixed in cooled down to -162 degC (-260 degF) to transition the gas into a liquid state. It is liquefied : …for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state… Håkan Jubel In a Tank Storage article, Radar Provides Precise Level Measurement in LNG Tank Gauging Systems , Emerson...

Asset Management Blog: IIoT for Equipment Condition Monitoring.

Even back when I was a young engineer in the 1980s, we had condition monitoring solutions for our large turbine generators and compressors on the offshore oil & gas production platforms in the Gulf of Mexico. Mike Boudreaux Condition monitoring technology has advanced greatly since then. Now, Industrial Internet of Things (IIoT)-based sensors can feed much of the data to enable more assets – not just rotating equipment...

Level Blog: Demonstrating Non-Contacting Radar Level Measurement

It’s been a struggle catching up after a busy CERAWeek last week and a Spring Break week, this week in Austin. Let’s close this short week with a look at one of the very accurate level measurement technologies—non-contacting radar. In this short 3+ minute YouTube video, Non-contacting Radar: Simple configuration with Rosemount 5408 , Emerson’s Jimmie Soderstrom contrasts non-contacting radar with guided wave radar technology...
