In prior posts, we've shared many flow measurement technologies, including averaging pitot tube flowmeters. Emerson's Katie Hausman shared a new video that the Rosemount measurement brand team has put together that explains how averaging pitot tube technology work....
According to an ISA presentation given by Process Automation Hall of Fame member, Greg McMillan, the most common measurement device is the differential pressure (DP) transmitter. It is most commonly used in level and flow measurement. Measuring the differential...
There'll be lots of news coming out next week at the Emerson Exchange Americas conference in Dallas/Fort Worth, Texas. I'll have a "Live" page to announce on Monday where we'll be gathering all the happenings to make it easier to follow the action, if you won't be...
It's been a week of travel, so we'll close it with a video from Emerson's Rosemount measurement team on how to install an Annubar averaging pitot tube flowmeter. The Youtube video shows the installation process for a Rosemount 485 Pak-Lok flowmeter. This device, used...
Update: Greg has published a post, Checklist for Compressor Surge Control Tips which should give you some things to consider for your centrifugal and axial compressors. Orginal post: It's great to questions from automation professionals from some of my posts built up...
The distillation process is one of the most common means of separating two or more components from a fluid. Ever handy Wikipedia defines it: Distillation is a method of separating mixtures based on differences in volatilities of components in a boiling liquid mixture....
You may recall from a post, Eliminating Temperature Effects in DP Level Measurement, a cool new technology—Rosemount 3015S Electronic Remote Sensors (ERS) system. To avoid some of the temperature and response time issues that I highlighted in the post with capillary...
A colleague alerted me to a series of fun videos from the Rosemount Measurement team. The videos star Emerson's Caitlin Breen and Daniel Lucey in the role of white lab-coated Rosemount 3051S Series instrumentation torture specialists. It's one thing to say your...
The old cliché, "time flies when you're having fun" applies to the many Emerson folks who had a hand in the development, launch, and widespread use of the Rosemount 3051S Series of pressure, DP [differential pressure] level, and DP flow transmitters. Congratulations...
Differential pressure (DP) measurement has long been used in tank and other vessel level measurement. Level is calculated by taking the difference in pressure divided by the specific gravity of the liquid. I caught up with Emerson's Anshuman Prasad, a member of the...
Those that read this blog regularly know that I rarely delve into controversial topics. The focus is much more about connecting readers with the experts we have all around Emerson Process Management. One of the few posts that caused a dust up was Response to...
If you have custody transfer applications in your plant and you're not already an expert on the subject, there's a great Control Engineering magazine article, Custody Transfer: Flowmeter as Cash Register. It's written by Emerson's Emerie (a.k.a. Butch) Dupuis and...
