In today’s process control systems, whichare applied in Water/Wastewater and in manyother industries, there are primarily two types ofsystems to choose from, open or closed. Thispresentation will look at process control and howit is applied and will take a close look at opensystems versus closed systems and the advan-tages of each.

The systems will be reviewed from both thehardware and software perspectives, with thegoal that the audience should takeaway an understanding of what open vs closedmeans and a better approach to making decisions when having to choose a process controller.

Discussion topics will include batch and continuous control, DCS, PLC, Instrumentation FieldBusses, Networks, and related items.

I took off a little early from work on Oct. 10th to make it to the ISA-LA Sectionmeeting on Introduction to Safety Instrumented Systems (SIS) and Critical Controls in theProcess Industry presented by Robin McCrea-Steele , Senior Safety Consultant /Director of PCS Business Development at Invensys - Premier Consulting Services. Anoverview of safety standard ANSI ISA S84.01 (IEC61511Mod) was presented, alongwith the definition of Safety Integrity Level (SIL) and a description of methods used forSIL assignment and verification. The Gas Company’s Energy Resource Center at 9240Firestone Blvd. in Downey, proves to be a very nice venue. Also, saw a few of my fellowOC members there taking advantage of this opportunity.

Our October meeting was held on the 11th in Fluor’s Irvine office near the UCICampus, and was titled Successful Execution Strategies, and Lessons Learned from an

LNG plant in Mexico using Main Automation Contractor (MAC). Romel S. Bhullar from Fluor, gave anexcellent presentation followed up with many recent site photos and questions from those in attendance. It wasgreat to see both of these meetings very well attended, demonstrating the continued upswing in the automationbusiness and the influx of many younger professionals eager to learn.

For those interested in staying current with latest technological innovations in the world of analysis, theproposed ISA-OC Analysis Division Educational Symposium is now taking shape due to the efforts of JohnQuerido, John Gong, Sandra Krauthamer and Paul Otteman. Target date is sometime in February 2007,and will most likely consist of a half-day schedule on a Saturday.

One last reminder: The ISA-OC/ISA-LA Annual Christmas Party is approaching soon, December 9, 2006.As you all know this includes dinner, raffles, award ceremony, silent auction, casino gambling, and socializing.Location is the Ramada Inn Suites and Hotel, 1089 Santa Anita Avenue, South El Monte (see the article in thismonth’s Chart for more information and how to get tickets). Hope to see you there.

Message from the DVP

Yours truly,Joe BinghamDistrict Vice-President, District 11, 2006 - 2007Chairman, Engineering, Science, & Technology policy for ISA, 2005-2006Chairman SP - 101, HMI’sMember of the Executive Board of ISA

I’m actually writing this article at 31Kfeet up in the air traveling from Philadelphiato Montreal, CA. Why, that’s another storythat I’ll tell you later.

Your ISA leaders just completed anotherweek of attending committees, meetings, andother functions at the leadership meeting inHouston, TX. The executive board voted onallocating 20% of the ISA reserves (around6.6 million dollars) to support ISA’s fivecompetences (Standards, Training, Certifica-

tion, Publishing, and Conferences & Exhibits) as well as provide itsmembership free standards. That’s right, soon you will all get access tothe standards for free. In the coming months I will continue to informyou on the changes that are happening at ISA for the better good of itsmembers.

Delegates from all section also officially elected Kim Dunn (of theLA section) as president elect secretary. Yes, this means that she will bethe youngest president ever and not to mention the fist female in ISAhistory.

ISA is at work for youOur Cal. Poly Pomona students came in second this year at the

international student games. They competed against eleven otheruniversities and collages. They did an awesome job. They were lead bynone other than Saif Rawas and his team Sandy Kwan, Steve Jankly,Amir Eshraghi lead by their advisor, Prof. Salomon Oldak.

As always, please let me know if you like my messages or thinkthat I’m way off track. Also please let me know if you have anyquestions, concerns, comments, etc. You can reach me at 714-625-9021or [email protected].


Now that the period for the governor toconsider bills is over, the California LegislativeCouncil of Professional Engineers (CLCPE) willbe approaching legislators and others inSacramento to test the winds for next year. Nowthat the summer election is over and thelegislature is out of session they will not bepreoccupied. After CLCPE has surveyed thesituation, a report on the next course of actionwill be given, according to a CLCPE spokesman.

As far as efforts to reform Californiaengineering licensing law and with SB246 nolonger a possibility, CPCPE considers the mosteffective course at this time may be through thecourts. Unfortunately this is a lengthy process,which is what the legislative process has turnedout to be, and more expensive, indicatesCLCPE.The Spinach Effect

The spinach contamination events recentlyin the news should be of great interest to peoplewho use engineering services. Unfortunately forthe public, safety is not considered a news-worthy topic until after a tragedy such as thishas occurred. In this case, AgriculturalEngineers (also a title license, like ControlSystems Engineers) will likely be at theforefront in the investigation and in developingmethods to prevent this from happening again.

Another development is the governorsigning the bill to reduce greenhouse emissions,which would seem to involve the services ofChemical Engineers (also a title license). As withthe spinach event, this situation will also bestudied by CLCPE.

CLCPE continues to press for engineeringregulation reform. No real activity takes placeuntil after the November elections.

You may have to look hard to find one, though. If you talk withthose in the industry, you already know that instrument techs are inshort supply. Next time you are talking with someone looking for acareer and who likes varied work and challenging work, invite them tothe next ISA section program or tour and introduce them to this field.

Some of us program controllers andcomputers to process data, prepare data graphs and written reportstranslating test results into meaningful terms.

We select, install, calibrate, manufacture, supply instrumentation,and develop specifications for nonstandard apparatus and equipment.They may make sketches and build or modify jibs, fixtures, instru-ments, and related apparatus. They also may verify the acceptabilityof devices which have been fabricated by craft workers or othertechnical personnel. In addition, technicians, troubleshoot, repair, andperform preventive maintenance on test apparatus and peripheralequipment.

Some info about instrumentation technicians... They test, certify,install, repair, inspect, maintain, and help to develop complex

instruments that measure and record changes in industrial environments.The process-controlled systems operated by these technicians are centralto the operation of such facilities as chemical plants, canneries, foodprocessing plants, air and water pollution control agencies, petroleumrefineries, and power plants.

Technicians test and record the effects of varying conditions, actualor simulated, such as vibration, temperature, humidity, pressure, differen-tial pressure, liquid flow and level, altitude, acceleration, pH, conductivity,stress, and chemical analysis. They prepare graphs and written reportstranslating test results into meaningful terms.

Technicians select, install, calibrate, and check out telemetering andrecording instruments and circuits. Using engineering data, and consideringthe limitations of the equipment being tested, they develop specificationsfor nonstandard apparatus and equipment.

They may make sketches and build or modify jibs, fixtures, instru-ments, and related apparatus. They also may verify the acceptability ofdevices which have been fabricated by craft workers or other technicalpersonnel. In addition, technicians, troubleshoot, repair, and performpreventive maintenance on test apparatus and peripheral equipment.

Some Instrumentation Technicians work as field service representa-tives who install and maintain equipment and systems at the customer’sworksite. In addition to providing preventive and corrective maintenance,

News, Photosand Feedbackfrom ISA Expo2006 are on theway!

If you were at ISA EXPO inHouston, we would like to hear whatyou liked and what you thought needs tobe improved. We have already hearing back fromseveral who attended or exhibited andplan to publish a summary of all thecomments in next month’s newsletter.

their duties may involve training the customer’s employees and advisingthem of proper procedures to use to avoid equipment breakdowns.

In the performance of their duties, technicians operate calculators,computers, testing devices, and laboratory equipment. They use draftingtools, complex electronic and mechanical instruments, and also useengineering handbooks and other reference materials.Working Conditions

Although working conditions vary widely for InstrumentationTechnicians, most work areas will be relatively new, modern, air-conditioned buildings that offer a pleasant working environment.Instrumentation Technicians may work in the engineering or prototypedepartment, in the main production department, or at their own testbenches. Due to the delicate nature of many electronics products,technicians may perform much of their work in “clean rooms” in whichthe temperature, humidity, and dust content of the air are carefullycontrolled. All workers in clean rooms wear masks, gloves and smocks orcoveralls, which are usually referred to as “bunny suits.” The work mayoccasionally require lifting up to 20 pounds, standing, stooping,climbing, and working in tight or confined control panels. Depending onthe worksite, technicians may be exposed to chemicals, extremetemperatures, pressures, and vacuum.Employment Outlook

The following information is from the California Projections ofEmployment published by the Labor Market Information Division. Thefigures represent the broad occupational group Electrical and ElectronicsEngineering Technicians and Technologists that includes InstrumentationTechnicians.

Estimated number of workers in 1993 49,250. Estimated number ofworkers in 2005 58,760. Estimated Growth 1993-2005 19%. (Thesefigures do not include self-employment or openings due to turnover.)

A projected increase of over 9,000 new jobs, combined with theestimated 14,000 workers leaving the labor force, were estimated tohave resulted in 23,000 job openings in California by the year 2005 forinstrumentation technicians.

The need for industry to modernize, install labor-saving equip-ment, and replace old systems with those featuring the latest technolo-gies assures a continuing need for Instrumentation Technicians.

The standard workweek is 40 hours, Monday through Friday.Many companies employ technicians on swing and night shifts. Nightshift employees can expect up to an additional 10 percent in pay.Most plants shut down twice a year to overhaul their continualoperating systems. These “turnarounds” (lasting one to three weekseach) can offer Instrument Technicians 12-16 hour work days, sevendays a week.

Field service technicians normally have the opportunity forunlimited overtime by being “on call” during their off-duty hours. Suchovertime work is sometimes compensated at time and one-half, ordouble time on holidays.Entrance Requirements and Training

Instrumentation Technicians must understand and applyelectronics theory. High school students interested in this field shouldstudy mathematics, general physics, and laboratory science. Thesejobs, according to representatives from personnel departments, willrequire at least two or three years experience, an Associate of Arts orScience degree, or completion of an Instrument Technician program at aprivate technical school.

California has several private and public two-year colleges andtechnical schools offering courses in instrumentation technology orengineering technology. Technicians learn hands-on laboratory skills as

Internet tip of the month

What Is RSS?The term “RSS” is appearing all over now, and it can be a good way

to keep up with new information. The following from the US Govern-ment website, www.firstgov.gov gives a basic introduction to this newtool.

What Is RSS?RSS stands for Really Simple Syndication. It’s an easy way for you

to keep up with information that’s important to you, and helps youavoid the conventional methods of browsing or searching for informationon websites. Now the content you want can be delivered directly to youwithout cluttering your inbox with e-mail messages. This content iscalled a “feed.”

RSS is written in the Internet coding language known as XML(eXtensible Markup Language), which is why you see RSS buttonscommonly labeled with the icon “XML.”

What Is an RSS Reader?An RSS reader is a small software program that collects and

displays RSS feeds. It allows you to scan headlines from a number ofnews sources in a central location.

Where Can I Get an RSS Reader?Some browsers, such as the current versions of Firefox and Safari

have built in RSS readers. If you’re using a browser that doesn’tcurrently support RSS, there are a variety of RSS readers available onthe web; some are free to download and others are available for pur-chase.

How Do I Use RSS Feeds?The first step is to choose an RSS reader. Each reader has a slightly

different way of adding a new feed, also called a “channel.” Follow thedirections for your reader but, in most cases, here’s how it works:

* Click on the link or small XML button near the feed you want.For example, FirstGov.gov Updates: News and Features. You’ll see apage displaying XML code.

* From your web browser’s address bar, copy the URL (webaddress). For example, the URL you would copy for FirstGov.govUpdates: News and Features is: http://www.firstgov.gov/rss/updates.xml.

* Paste that URL into the “Add New Channel” section of thereader. The RSS feed will start to display and regularly update theheadlines for you.

How to subscribe to FirstGov.gov RSS Feeds* Subscribe to the FirstGov.gov Updates - News and Features RSS

Feed - Stay on top of important government news and information withthe FirstGov.gov Updates RSS feed. We’ll revise this feed when we addnews and featured content on the FirstGov.gov website.

* Subscribe to the Popular Government Questions fromFirstGov.gov RSS Feed - Our government questions RSS feed will keepyou informed with the most popular and useful questions and answersrelated to the U.S. government from our frequently asked questionsdatabase. Our database contains thousands of answers to the questionsthe public asks our 1 (800) FED INFO call center.

By Linda Meyers, Product Manager George Fischer Signet, Inc.

“Units of Operation” is a term that describes a common processthat can be found among many industrial plants. Engineers design aplant with these units in mind, as the units make up a good portion ofthe facility and usually have specific functions such as mixing, neutraliz-ing, or separation of fluids. Other common units include (but are notlimited to), cooling towers, boilers, scrubbers, and chemical injectionsystems. An entire plant can be built with numerous units combinedwith more specific processes for each individual application.

In last month’s newsletter, deionization methods and systems werediscussed. Because deionized water has very low mineral content, it iscommonly used in the beginning or middle stages of a productionprocess. At the end of the production cycle, dirty wastewater iscollected, treated, and discharged. Due to environmental issues, localwater authorities require the neutralization of industrial wastewaterdischarge to protect the ecological systems in the surrounding lakes,rivers, and oceans, or to protect the local sewer networks and treatmentplant. So, this month’s discussion will focus on wastewater neutraliza-tion.

The wastewater neutralization process can be complex anddifferent for each industrial location. The use of acidic and causticchemicals to neutralize the discharge is common practice among manyindustries since they are both inexpensive and effective. Each facilitymust have a good understanding of the wastewater chemical make up,

buffering capacity (alkalinity), flow rate, and sewer discharge require-ments (pH, suspended solids, dissolved solids etc.) in order to select theproper chemical neutralization treatment program.

It is most effective to perform the neutralization process in a tankrather than in a pipe at the final process or discharge. The constructionof the neutralization tank should include a pH sensor that is mounted in

Professional Training & Advancement

PLC, instrumentation, CCST training series

A series of instrumentation courses hasbeen scheduled this year by the Los AngelesSection. Classes will be held on weekdayevenings. Each course will consist of nine

classroom and lab hours. Courses will beconducted by professional instrumentationtrainers and are not product specific. Profes-sional Development Certificates will be awardedto attendees.

Instrumentation Level 1Training This course consists of threeevenings. This class will give anyonenew to the industry basic practicalworking knowledge in the areas offlow, temperature, pressure and levelinstrumentation. Some of the practicalthings you will learn include how tospecify and order thermocouples,flowmeters and other instrumentationdevices. Instructors: Neil Finch, KevinO’Neill and Gary Penny. Two of 20 seats werestill open as of October 27th.- Tues, Nov 7 - Instrumentation Physics- Tues, Nov 21 - Calibration Practices &Training Lab- Tues, Nov 28 - Detailed Review of Flow,Temperature, Pressure & Level Instrumentationand Applications

a position that allows easy removal of the sensor for periodic mainte-nance and calibration. The tank will also commonly have a mixing motorand chemical injection pumps located opposite of the pH sensor.

Sensors that measure pH are crucial in the neutralization process;however, all pH sensors are not the same. Many neutralization processescontain materials or chemicals that can cause premature senor failure bycontamination of the internal reference solution. In these cases, a morerugged sensor, such as one with a differential reference, will extend thelife of the sensor.

Besides pH, other measurements in the neutralization processinclude flow, ORP, conductivity, and level. Flow is measured to Trackthe amount of influent water being treated and enables recordings of theamount of processed waste water being discharged to the sewer. ORPmeasurements monitor the disinfection ability of the chlorine that may beinjected into the wastewater. Conductivity may be monitored to adjustconductivity levels being discharged to the sewer, preventing high saltpollution. Level measurements are commonly done in the chemical andneutralization tanks.

Keeping in the theme of cleaning water, next month’s Unit ofOperations article will look at disinfection by the use of ozone.
