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 Solutions Optimized for Cold Climates: Improved Response Time, highlights the importance of selecting the right […]

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 release of the dissolved gas is referred to as “Outgassing.” You […]

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 measurements make an assumption of the density of the fluid. I […]

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 measurement repeatability, and overall improved measurement stability. Emerson’s Michael Olivier shared with me improvements that have been made to the Rosemount 3051S […]
