Advanced Level Measurement Instrumentation
Jim Cahill
Given the weather extremes we’ve experienced here in the U.S. in recent weeks, manufacturers and producers with outdoor production facilities need accurate and self-diagnosing instrumentation to assure reliable operations. Level measurements are one critical area where this is especially true. In a Flow Control article, Advanced level instrumentation improves performance and safety , Emerson’s Nicole Meidl and Megan…

Making the Most of Built-In Proof-Testing for Your Safety Lifecycle Management
Jim Cahill
It’s not surprising that safety is a top priority for plant managers and operators, but minimizing risk in these environments is no simple task. Safety Instrumented Systems (SIS) are failsafes built into critical processes to maintain maximum operational integrity. These systems consist of independent sensors and control equipment in series in order to detect abnormal operating conditions. Should an issue arise, the SIS…

Multiple Systems Working Together Prevent Tank Overfill Disasters
Jim Cahill
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 chemicals can cause an environmental incident under the best circumstances, but also a high probability of an explosion and fire. Given the costs in lost product…

Low Dielectric Radar Level Measurement
Jim Cahill
Guided wave level measurement technology works by sending low-energy microwave pulses along a metal probe which is then reflected by the surfaces. The probe is in direct contact with the media and detects a level when reaching a media with a different dielectric constant. It calculates the distance to the surface, which is then subtracted from the total length to calculate the level. For applications with fluids with…

Tips for Accurate DP Level Measurements
Jim Cahill
Nicole Meidl 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 divided by the specific gravity of the liquid. I share this as background for a Processing magazine article, Better ways to use differential…

Frequency Modulation for Improved Radar Level Measurement
Jim Cahill
Ingemar Serneby 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 subtle changes in the frequency of the signal. In a Flow Control magazine article, How frequency modulation can improve effectiveness…

Successfully Applying Non-Contacting Radar in Black Liquor Mixing Tanks
Jim Cahill
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 papermaking process. This digesting process turns the white liquor into black liquor, which contains : …lignin fragments, carbohydrates from the breakdown of…

Improving Floating Roof Tank Performance
Jim Cahill
Christoffer Hoffmann 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 Storage Terminals magazine article, Staying on the Radar , shared some thoughts from Emerson’s Christoffer Hoffmann on avoiding…
