In an automation.com article, Emerson’s Michael Flesch explains how advances in DP flow metering technology solve measurement challenges of compressible fluids. One of the perpetual instrumentation challenges that engineering students and working technicians face is...
The latest Innovations in Process Control publication by the Emerson team in Europe has an article on where additional measurements can help identify opportunities to reduce energy consumption and improve operations. For readers who have English as a second language,...
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...
One of the most proven ways to measure flow rate is through differential pressure measurement. By creating an obstruction in the flow of fluid, a difference in pressure is created upstream and downstream of the obstruction. In this 3:12 educational YouTube video, How...
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...
Here is a final recorded livestreamed presentation I captured last week at the Emerson Exchange. Emerson's Brian Fieser and Joel Lemke presented 40 CFR 98 Tier 4 Greenhouse Gas Reporting with Stack Emissions Flow Meter. Unfortunately, the recording is joined in...
