Pressure Drop across Control Valves
Let's end this short week for the United States of America's 4th of July Independence Day holiday with an educational video from Emerson's Fisher Valves & Instruments YouTube channel. The video, Control Valve Sizing Basics: What is Pressure Drop?, describes what...
Selecting the Right DP Level Device for the Temperature Conditions
With the season in change from summer to autumn here in the northern hemisphere, let's look at differential pressure (DP) level measurement performance at various temperature ranges and particularly at cold weather performance. This quick 2:35 YouTube video, DP Level...
Sizing Control Valves for Outgassing Applications
Think about what occurs when you open a bottle of champagne. Immediately the pressure inside the bottle drops to atmospheric pressure. This is below the pressure that allows the dissolved carbon dioxide to remain in solution, thus the CO2 gas is released. This sudden...
Calculating Fluid Density Changes in Foundation Fieldbus Devices
I received this question on density measurement and wanted to share what I found out. I understand all dP flow measurements are affected by the density of the fluid (liquid or gas) flowing through orifice, annubar, pitot tube, etc. Most dP measurements in process...
Ways to Improve Plant Performance via Pressure Instrumentation
Embedded diagnostics in smart instrumentation has played a role in safer, more efficient and reliable plants for decades in the process industries. As the power of the microcontrollers at the heart of these intelligent devices grows, so do the reliability, accuracy...
Extending Measurement Device Stability to 15 Years
One of the benefits of advancing technologies can be increased reliability. For measurement devices in the processing industries, these technology improvements can mean increased operations and maintenance productivity through extended calibration intervals, improved...
Upgrading Rosemount 1151 to 3051 Pressure Transmitters
The venerable Rosemount 1151 pressure transmitter was introduced all the way back in 1969. It combined 4–20 mA electronics with capacitance technology. In my first job post college, I worked as a project engineer out of New Orleans on offshore oil & gas platforms...
Ordering Rosemount Measurement Instrumentation Extends to Australia
Online purchasing and support for Rosemount measurement products has been available here in the U.S. A colleague shared some news with me that this store has now expanded to process manufacturers and producers in Australia. Emerson Process Management Australia Online...
How Pitot Tube Flow Measurement Works
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....
Measuring Flow on Fluid Streams
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...
MultiVariable Wireless Measurements
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...
