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.
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...
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...
Boiler steam drum level control is critical in electrical power generation. Too high a level can mean water aspirating into the steam lines and causing damage to the turbine generator blades downstream. Too low a level can cause the boiler to dry and overheat. In a...
For oil & gas well pads not connected to pipelines, custody transfer of the produced oil and produced water occurs via truck transport. The trucks load oil from holding tanks and require accurate measurements for the custody transfer from producer. Similarly, this...
Last year during the epic rains of Hurricane Harvey, more than 15 floating roof storage tanks in the Texas Gulf coast region failed during this record-setting storm. These failures resulted in a combined 3.1 million pounds of volatile chemicals being released into the...
Electronics technology continues to rapidly advance. For instrumentation and automation, this means that capabilities can continue to be added. But how do automation suppliers keep from adding complexity with added capabilities? In an Automation.com article, Advanced...
Levels of intermittent, renewable sources of energy for the electrical grids around the globe continue to grow. Power plants designed for more consistent, base load operation are under greater stress. In this recorded Power magazine webcast, Optimizing Level Control...
I was alerted to a great new whitepaper about floating roof tank hazards and solutions by our Rosemount radar level measurement and tank gauging systems team including Emerson's Per Skogberg. The whitepaper, by PEMY Consulting's Philip E. Myers, describes the types,...
While oil and gas production processing equipment can separate the gas, oil, basic sediment and water from the production stream, this equipment typically can't separate the salt that can be found in solution in the oil. At high enough concentrations, this salt can...
Floating roofs are used on storage tanks to minimize vapor space between the top of the tank and the level of the liquid, typically a petroleum-based product, inside the tank. Per the External floating roof tank Wikipedia entry: The roof rises and falls with the...
