For those here in North America, there is a good chance you’re braving extremely cold weather today. The Weather Channel captures the situation well in a post, Arctic Cold Blast Continues; Wind Chill Alerts For Over Half U.S. Population. And Canada makes this appear balmy. Back at the Emerson Exchange conference in Orlando this past […]

The distillation process is used in many industries to separate mixtures into components. It is defined as: …a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat. Emerson’s Daniel Lucey has written an Intech article, […]

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 tubing, this technology includes: Two 3051S pressure transmitter… mounted on the high and low […]

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 Rosemount pressure measurement team. He described four traditional ways of measuring the […]
