At the Emerson Exchange Americas Virtual Series, Emerson’s Felix Johansson and Patricia Borghede introduce the world’s first non-contacting radar level transmitter designed for food & beverage applications.
In Hydrocarbon Engineering’s Tanks & Terminals Supplement, Emerson’s Helena Hjortsberg looks at all the elements of a comprehensive overfill prevention system in her article, A Coordinated Strategy. Overfilling a tank storing hydrocarbons or other flammable...
For applications with fluids with very low dielectric constants and over very long ranges, probe end projection technology enables accurate measurements. This under one-minute video, Rosemount 5303 guided wave radar with probe end projection: How it works., succinctly explains how it works.
Differential pressure (DP) for liquid level measurement works by measuring the hydrostatic head pressure at the bottom of the vessel and the specific gravity of the liquid. The height of the liquid in inches is the pressure of the liquid column in inches of water...
What is the purpose of your level measurement? If you know the answer to that I highly recommend an Intech article, How to measure liquid level in vessels, by Emerson's Lydia Miller. This article is but one of a number of excellent learning articles in the...
For those that still listen to FM radio over the airwaves given our increasingly streaming digital world, you may know that the FM stands for "frequency modulation". Information such as the music you hear on an FM music station is encoded in the radio signal through...
In the Kraft pulping process, wood fibers are separated, and resinous materials removed, using an alkaline (typically sodium hydroxide and sodium sulfide) cooking liquor, also known as white liquor. This process converts wood into cellulosic pulp used in the...
Bulk liquid storage terminals are a critical component in the energy industry supply chain between production and distribution. Floating roof tanks are commonly used to avoid having a vapor space or ullage between the liquid level and roof found in fixed-roof tanks. A...
Christoffer Widahl and Jimmie Soderstrom presented The New Normal for Process Radar—The New Two-Wire FMCW [Frequency-Modulated Continuous Wave] Radars are Here!, at the 2019 Emerson Exchange conference. Jimmie opened with a question, "Why measure level?" It is to...
Just imagine that you're an operator in a facility that makes concentrated orange juice and the production process requires you to manually check the levels of large processing tanks in the freezing process conditions. Parkas and gloves are a part of your work attire....
Here's a quick one-minute YouTube video, Rosemount 5408 How To - Mechanical Installation showing the mechanical installation of a Rosemount 5408 Non-Contacting Radar level transmitter. Not much to say other than it looks very straight forward. Visit the Non-Contacting...
Each safety instrumented function (SIF) including its sensor, logic solver and final control element must be periodically tested to make sure it will perform as designed in the event of a safety demand. These "proof tests" help to uncover and failure conditions which...
