Moving Beyond Local Pressure Gauge Readings
Walk around most any industrial process manufacturing or production process and you'll likely see pressure gauges providing feedback to operators who walk by. According to the Pressure Gauge entry in Encyclopedia.com, this technology: …was invented by French...
Using Flushing/Drip/Calibration Rings in Pressure and Level Measurements
If you work with pressure measurement instrumentation, you may have heard the phrases drip rings, flushing rings or calibration rings. These are used for pressure and differential pressure (DP) level measurement devices where diaphragm seals are used. I bring this up...
Measurement Repeatability in CIP and SIP Operations
One only has to do a Google image search on pharmaceutical equipment to see the clean, sanitary conditions required for pharmaceutical and biopharmaceutical processing. The measurement instrumentation must be able to handle the tough conditions when cleaning and...
Rugged Downhole Pressure and Temperature Measurement
I saw a recent news item, Emerson introduces digital, +175°C, high-precision pressure and temperature transmitter designed for corrosive harsh downhole measurements, and wanted to find out more about the application for this technology. I caught up with Emerson's Joe...
Accurate and Repeatable Measurements in Pharmaceutical and Biotech Manufacturing
A Pharmaceutical Manufacturing magazine study revealed that pharmaceutical and biotech manufacturers were challenged to achieve batch after batch repeatability. I came across a recently published whitepaper, Consistency and Repeatability Through Accurate Measurements....
High Pressure and Temperature Sensors for Subsurface and Surface Oil and Gas Applications
In a Reuters article, Forget fracking. Choking, lifting latest efforts to stem U.S. shale bust, Andrew Slaughter, director for the Deloitte Center for Energy Solutions stated: Production optimization is going to be the next phase of the shale revolution… The low price...
Ways to Improve Plant Performance via Pressure Instrumentation
Embedded diagnostics in smart instrumentation has played a role in safer, more efficient and reliable plants for decades in the process industries. As the power of the microcontrollers at the heart of these intelligent devices grows, so do the reliability, accuracy...
Ways to Improve Pump Reliability
A U.S. Department of Energy study on pump life cycle costs notes that maintenance and energy costs make up the vast majority of lifecycle costs. Pumps that are critical to the operation of the process typically are installed with online condition-based monitoring...
Monitoring Control Loops for Leakage Current and Increased Resistance
Control systems rely on the signals coming back from measurement devices to perform control operations and provide feedback to operators. Unfortunately the signal from these devices can be impacted by several conditions. These conditions include damage and corrosion,...
Multiphase Metering 101 by Roxar and Rosemount
Emerson's Svein Erik Gregersen and John Goetz discussed oil & gas multiphase metering. Their abstract: For over 20 years, Roxar has delivered innovative multiphase (oil, gas, and water) flow measurement solutions to offshore & subsea oil and gas customers....
New Measurement Best Practices for Cold Climates
Emerson's Mark Menezes perfectly timed presentation for northern hemisphere process manufacturers and producers shares his experiences for improving measurements in cold weather. His abstract: Installations of instrumentation in cold climates (where temperature can...
