IIoT in Steps for Monitoring Valve Health

Emerson's Jonas Berge

Manufacturers and producers can improve safety, reliability and efficiency by applying additional sensors, analytics and experts. Difficulties in installation have held back these improvements, but the Industrial Internet of Things (IIoT) technologies have significantly reduced these barriers.

Valve magazine: Monitoring Valve Health via the InternetOne example of IIoT in action is featured in a Valve magazine article, Monitoring Valve Health via the Internet.

Emerson’s Jonas Berge opens the article:

Most valve end users are already using smart valve positioners on some control valves, but they may not have time to check the valve diagnostics software to notice if any valves are developing problems. Imagine instead simply getting a weekly report listing which valves need attention.

Jonas explains that the Industrial Internet of Things opens the ability to get these diagnostics into the right hands wherever the valve experts are located. These could be in-house valve experts, perhaps located remotely, or provided as a service by the valve supplier.

Jonas describes a step-by-step approach: Continue Reading

Adding Wireless Level Switches for Storage Tank Overfill Prevention

Control Engineering Asia: Wireless vibrating fork technology enables Hengyang Petrochemical to implement cost-effective overfill prevention solutionStorage tanks holding volatile fluids must have reliable level measurements to avoid unsafe overfill conditions. A Control Engineering Asia article, Wireless vibrating fork technology enables Hengyang Petrochemical to implement cost-effective overfill prevention solution, describes how this petrochemical producer sought to reduce the risk of overfill conditions.

The plant had existing non-contacting radar level measurement devices to measure continuous level changes but wanted to comply with a recent industry standard for the additional use of an independent overfill prevention sensor. The plant engineering staff approached the Emerson team for a recommendation.

A solution based on vibrating forks was recommended because the technology is less prone to failure and requires minimal maintenance.

The [hyperlink added]:

Rosemount™ 2160 Wireless Vibrating Fork Level Switches were selected to provide overfill prevention. The industry’s first WirelessHART® point level switch enables level detection to be made in locations previously inaccessible or cost-prohibitive for wired devices.

Device health diagnostics in these level switches include: Continue Reading

Connecting the Experts More Closely to You

It’s been a light posting week. I’ve been in Houston working with Emerson subject matter experts from across many of the Emerson Automation Solutions business units. Look for a number of new Emerson voices sharing their expertise here on the blog and in Emerson Exchange 365, LinkedIn and Twitter.

Here’s a few photos of the group from our sessions at the Emerson Actuation Technologies global headquarters office.

Tank Blanketing Pressure Regulation Calculations

Emerson's Steve Attri

In an earlier post, Sizing Tank Blanketing Regulators, we described changes in the API Standard 2000 – Venting Atmosphere and Low-Pressure Storage Tanks with the release of the 7th edition. Emerson’s Steve Attri highlighted the changes from the prior versions of the standard and how these changes affected the sizing requirements of tank blanketing pressure regulators.

I received an email with some questions about the post. I wanted to share a genericized version of the questions and Steve’s response in the hopes that it may help if you have similar questions. Here are the questions: Continue Reading
