Differential pressure (DP) is one of the most used and proven technologies for flow measurement. With averaging pitot tube (APT) technology, the impact pressure is sensed on the front of the device as the flow initially approaches the obstruction or bluff body which...
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....
The ways to measure gas and liquid flow are numerous. In prior posts, we've highlighted Annubar technology, which is similar to pitot tube technology. From Wikipedia: The biggest difference between an annubar and a pitot tube is that an annubar takes multiple samples...
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...
Emerson's Joel Lemke, Bob Sabin, and Scott Pettigrew presented Instrumentation and End Devices Needed for Improved Boiler Operation at the 2012 Emerson Exchange. Their abstract:While boilers are critical to plant/mill operation and business results, their performance...
An industry commitment and new technologies are contributing to cleaner metals and mining operations. Emerson's Michael Pearson, a member of the Rosemount Measurement team and metals and mining industry team, shares examples of the progress being made. Mining and...
Emerson's Rick Belin presented a session, DP Flow for Dummies, to share some of the best practices and pitfalls to avoid in differential pressure (DP) flow measurement. He cited many reasons from being well understood to being accepted practice in many applications,...
Emerson's Sam Thiara and Scott Pettigrew presented a case study on a steel producer looking to drive energy efficiency solutions to minimize costs and emissions. The objectives of the first project was to reduce CO2 emissions and dust in the facility and reduce...
A person searching on the subject of gas-fired heaters came upon one of the many posts here on this blog. He wanted to know: Is there any International standard or code compliance to measure or monitor the gases (like type of gas and range, etc.) in the gas fired...
A week ago, I highlighted a whitepaper sharing some of the advantages in top-mounting DP flow transmitters in steam applications. The whitepaper's author, Emily Vinella, pointed me to a presentation, What Do You Know About Wireless DP Flow?, which will be given by...
I connected with Emerson's Don Verhaagen and Emily Vinella and got my hands on a whitepaper on DP (differential pressure) flowmeter installations in steam applications. The whitepaper, Top Mount Installation for DP Flowmeters in Steam Service, describes conditions...
