Across many industries, level measurements are critical ones for safe and reliable operations. This is true for the water and wastewater industries. The choice of technologies for these measurements is broad, especially since they fall into two categories point-based...
Safety instrumented systems (SIS) include the sensor(s), final control element(s) and logic solver(s) for each of the safety instrumented functions (SIFs) in the SIS. To verify the SIFs are performing the amount of risk reduction intended for their application, they...
For electrical power producers, the phrase "heat rate" refers to the efficiency of the power plant. It is defined as the thermal energy in divided by the electrical energy out. Emerson's Lydia Miller let me know about a new whitepaper, Using Automation to Improve...
Articles such as Oil & Gas iQ's Five Deadliest Onshore Oil & Gas Blasts remind us of the critical importance and focus that is required for process and personnel safety. I lived in New Orleans at the time of one of the five mentioned. The accident occurred...
Emerson's Hampus Regnér and Christoffer Widahl presented Increase Safety and Efficiency With New Proof Test Method at the Denver Emerson Exchange conference. Here is their presentation abstract: A functional proof test of a high level alarm (HLA) is required as a key...
I've always held a fascination for offshore oil and gas production. It was my first job out of school as a newly minted Electrical Engineer working as a systems engineer out of New Orleans. Technologies have advanced quite a bit since that time back in the mid-to-late...
Yesterday, we looked at some applications for wireless measurement in upstream and downstream oil production. Today, let's look specifically at wireless level measurement in oil & gas production. In this quick 1:48 YouTube video, Wireless Level Measurement...
In an earlier post, Avoiding Cold Climate Measurement Challenges, we mentioned a thermal range expander for differential pressure (DP) level measurement, which can be applied in application with higher process temperatures and lower ambient temperatures. Emerson's...
A Process Engineering magazine article, Level best, poses a question: Has the deployment of level measurement devices changed in the wake of the Buncefield [UK] disaster? The article's author connects with several instrumentation suppliers including Emerson's...
Emerson's Cathy Ershen and Jim Elchook shared a case study on geothermal power generation. Their abstract: H2S abatement may be required to meet local environmental regulations for a geothermal plant. At Calpine's Geysers, a number of the operating power plants have...
The venerable Rosemount 1151 pressure transmitter was introduced all the way back in 1969. It combined 4–20 mA electronics with capacitance technology. In my first job post college, I worked as a project engineer out of New Orleans on offshore oil & gas platforms...
Level measurement can be tricky, especially when the fluid being measured has changing density and specific gravity. Emerson's Cathy Ershen alerted me to a paper she, Emerson's Pat Carroll and Calpine's Anthony Derenia had published at the Geothermal Library. The...
