Bulk liquid storage tanks often contain fluids that are hazardous, flammable and/or explosive. These tanks require not only a control system to control levels but and overfill prevention system (OPS) as layer of protection beyond the control system. This basic process...
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...
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...
If you are unfamiliar with cryogenic processes such as those found liquefied natural gas (LNG) plants, then you may be unaware of some of their unique challenges. One big one is overfill prevention and inventory measurement for cryogenic storage tanks. A cryogenic...
A pulp mill: …converts wood chips or other plant fibre source into a thick fibre board which can be shipped to a paper mill for further processing. Level measurements can be challenging in pulp manufacturing process. In a Pulp-paperworld article, Radar Technology...
Liquefied natural gas is methane with some ethane possibly mixed in cooled down to -162 degC (-260 degF) to transition the gas into a liquid state. It is liquefied: …for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of...
It's been a struggle catching up after a busy CERAWeek last week and a Spring Break week, this week in Austin. Let's close this short week with a look at one of the very accurate level measurement technologies—non-contacting radar. In this short 3+ minute YouTube...
Let's end the week with a quick look at how some instrumentation protects against intermittent power outages. This short, 1-minute Youtube video, How to Secure Safe Operations During Power Outages shows the power reserve function of the Rosemount 5408 level...
