A Day in the Life of an Analytical Support Rep – What Instrument Best Replaces an Older Model? It Depends.

By Randy Young and Pete Anson

My day started with a big cup of coffee in hand and an eye on my email. I was reading through them and prioritizing accordingly. Then, one email caught my eye. It was from Jaime in the Netherlands. He worked for a water bottling company and was looking to RAI_Image_RandyYoung_140802_optimizedupdate their current Rosemount Analytical equipment (4-wire analyzer1055-01-11-26) with one of our newer models. He read about it while browsing through one of our technical blogs at www.AnalyticExpert.com.

I started by asking him questions regarding their current setup: the model number of the analyzer and the sensor; his power requirements; as well as the type and number of measurements. Upon receiving his fast reply, I immediately began working on it. I didn’t have much personal experience with his equipment since it was one of the older models, but I have the best resources. After a quick discussion with the product manager, Pete Anson, I determined the features and options of the model Jaime had been using and discovered that the most direct replacement for Jaime’s old model is the improved 1056 four-wire analyzer. But that raised some questions Jaime hadn’t known to ask.

You see, while the 1056 is extremely high performance for a “general use” instrument, there could be circumstances under which the higher-end 56 advanced dual-input analyzer might be the best and most cost-effective option. The reason is that the 56 offers capabilities that might reduce costs for the customer in other areas of the plant. By rethinking the way some essential functions are performed, plant managers like Jaime can turn their liquid analyzer into a sophisticated plant machine.

56Many plants require the use of a data or event logger and/or a data historian to provide an audit trail for fulfillment of regulatory requirements or to meet internal reporting policies. I asked Jaime and discovered that his plant does require reporting. A standalone data logger can cost from $200 to $1,000, plus installation. The 56 analyzer, however, has a built-in data logger that can capture measurement data from both the process and the instrument – a dozen or more live values – from two channels every 30 seconds for 30 days. Jaime was pretty excited about this capability when I described it since he would get the reporting at no additional cost.

He also liked the idea of the two input channels. I explained to him that the channels can not only record more than one liquid parameter such as pH and conductivity or ozone, but also flow which has to be reported regularly. Using the 56 for this function can save the cost of additional analyzers. Since his outfall points are often on the periphery of the plant, I explained to Jaime that he would be able to use the 56 with wireless to transmit flow data from those points, saving him a ton of personnel and maintenance time.

I even dangled the possibility of using the 56 as a control device in certain functions. While the 56 has the traditional water treatment functions and control, which include on/off control, on/off control with delay (to allow time for mixing), and an interval time for sensor cleaning, there is a lot more control capability in the 56.  It can not only do standard PID and TPC (Duty Cycle) control on one or all of its 4 analog outputs and relays, but can also power and receive the signal of any two-wire transmitter, input its measurement and apply PID or TPC control to the measurement, which can be pressure, temperature or whatever. The 56 can be a single station controller.

After our email discussion, Jaime considered the many high-end features of the 1056 versus the potential savings the 56 could represent both now and in the future. Wisely, I think in his case, he opted for the 56 since it gave him a huge jump in flexibility over his older Emerson analyzer.

A great solution-oriented conversation. Consider it solved. Okay, who’s next? Booyah!

At Emerson, “Exchange” is a Year-Round, Worldwide Engagement

Saving money, enhancing efficiency, finding real-world solutions to industrial problems, sharing ideas, stimulating new projects, meeting friends, and having fun – these are just some of the benefits people discover at Emerson Exchange. The Emerson Global User’s Exchange, September 30 – October 4, at the Gaylord Texan Hotel and Convention Center in Grapevine, Texas, offers participants an impressive array of workshops, courses, industry forums, technology exhibits, and the chance to network and share ideas. It’s coming right up and we hope you already have your reservations!

But stimulating interaction among Emerson users and staff isn’t limited to the annual meetings each year. Engagement with peers and problem solving goes on at Emerson Exchange 365, the peer-to-peer online user’s community. All you have to do is click to enter important worldwide discussions and problem-solving forums. Engagement also continues right here on the Analytic Expert Blog, and on the Rosemount Analytical Facebook Page and Twitter sites where users ask questions and solve problems.

EEvideoHere is a video that shares some of the actual experience of Emerson Global User’s Exchange. We hope this tempts you to make it to Texas on September 30! But even more, we think you’ll get a sense of the interaction and engagement that is possible with other Emerson users and staff every day of the year by joining one or more social media sites.

And here is a list of the presentations being done by our Rosemount Analytical experts:

  • “Instrumentation for Direct Turbine Control of a 400 MW Natural Gas Fired Turbine with Ultra Low NOx Emissions” by Michael Kamphus
  • “Calibration Best Practices for Electrochemical Analyzers” by Jim Gray
  • “Fixed Gas and Flame Detection Installation Best Practices” by Geoff Wilson
  • “Single Digit NOx – Using Active Flue Gas Recirculation in Conjunction with Low NOx Burners” by Doug Simmers

Are you joining us in Texas? Advanced Registration – which saves you $200 – ends soon! Register now and join us!
