We sometimes read about plant disasters in the news, and every so often the cause has been a manual valve which was believed to be closed but was actually open.

The information did not get passed on to the new shift crew at the shift change. Had they known the valve was open, had they had that crucial piece of information, the disaster might not have happened.

For the Instrument Engineer. These are the top ten headaches that the engineers and designers face on a daily basis. Register to read the full paper here. But should we be shocked by this figure? Surely such a complex discipline necessarily comes with a high price tag? Expense is inevitable, certainly. But wastefulness is unforgivable.

Unfortunately, the technology used to plan and design electrical systems, just like that used to design instrumentation and control systems, is often just that — wasteful. Clearly, the electrical disciplines should have engineering and design tools as powerful as those used for 3D design in plant layout or ship design. This white paper details these tools. A lean approach requires the ability to handle change more effectively early on the design process and manage change, communicating it effectively across teams and disciplines. If we can eradicate the iterations and reworks in design and form the design right from the outset, we will ensure that everyone in the project execution is equipped with the latest and most accurate information about the project — this business paper challenges that premise.

The ideology does not have the flexibility needed to cope with client, legal, contractor and environmental changes which influence scope changes throughout the project.

Search Engine for International Standards - This is useful. Instrument Index - An Instrument index is a document containing list of instrument devices within a plant.

The Instrument index includes tag number of all physical instruments e. The Instrument index is created at the beginning of project and considered as a live document which should be kept updated even though the plant has been operated. Control and Field Instrumentation Documentation - To successfully work with and design control systems, it is essential to understand the documents that are typically used to illustrate process control and associated field instrumentation.

The documentation of process control and associated field instrumentation is normally created by the engineering firm that designs and constructs the plant. The company that commissioned the plant may have an internal documentation standard the engineering firm will be required to follow - An excellent document from ISA. Join the ISA here it is good value! The Differences between Watts and Volt Amps - Steve Mackay - I often get questions about the practical differences between watts W and volt-amperes VA ; mainly from our civil and mechanical engineering fraternity; but surprisingly also from some electrical types.

As you would know, electrical products generally indicate both to show how much energy and current they draw. This Blog details a quick summary of the differences with some interesting alternative calculations to work out total VA.

Before this publication, little guidance was available for installers and inspectors on how to evaluate electrical equipment that has been exposed to heat and fire residue. Electrical Safety from the Ground Up - Proper Grounding and Bonding is Critical for Electrical Workplace Safety - Reza Tajali - Risks associated with shock and electrocutions from inadvertent contact with energized parts have long been recognized as a threat to electrical workers.

In recent years, OSHA and industry associations recognized the severity and urgency of the situation which resulted in the development of new standards for electrical workplace safety. In essence, they mandate that work on electrical equipment must be performed in a manner that does not expose the worker to undue risk of injury. While arc flash awareness has been growing as well it should , the dangers of shock and electrocution should not be overlooked. In an average eight-hour day, 16 workers require time off the job to recover due to electrically induced injuries - from Schneider Electric Engineering Services and Plant Engineering.

The Forum will provide a platform to help industry understand the role of various regulators in different states, and identify key issues in achieving compliance throughout Australia. The Forum will focus on the impacts and practical applications of electrical requirements, reforms and harmonisation efforts.

Selection of topics to date include:. The Following are from our sponsor McCrometer. Electromagnetic flow meters are typically the meter of choice when considering cost, accuracy, and longevity. Here are some tips that can assist with ensuring that the electromagnetic flow meter is the right choice.

Next Generation Mag Meter Solves Water Treatment Plants Tight Installation Dilemma - Michelle Pawlowicz - The flow meter selected is ideal for the needs of the Lake Huron WTP because it is economical for large line sizes, features a compact insertion design for ease of installation in compact spaces with limited access points and can be installed and maintained without shutting down flow.

Flow Measurement in a Pump Station - Michelle Pawlowicz - Water losses within the distribution system can raise costs for both plants and customers. As a result, many municipal plants are being forced to run their plants and operations as efficiently as possible. Water supply issues, budget constraints and environmental concerns have raised the importance of understanding plant production and losses.

Acquiring the ability to measure flow effectively at various points within the distribution system will provide data regarding the quantity of water pumped into a treatment facility, and the quantity of water pumped from the treatment facility throughout the distribution system. Measuring flow in each pump station will provide a reference point to these quantities of water flowing through the pump station. This will assist with maintenance planning, provide data references for potential loss analysis and accurately determine how much water is transported for billing and revenue processes.

Ultrasonic Flowmeters. System Smoke Detectors - The purpose of this excellent guide is to provide information concerning the proper application of smoke detectors used in conjunction with fire alarm systems. The guide outlines basic principles that should be considered in the application of early warning fire and smoke detection devices. It presents operating characteristics of detectors and environmental factors, which may aid, delay, or prevent their operation - from System Sensor.

Each type of detector having differing flame detection performance not just by type but also from manufacturer to manufacturer. This article looks at the more fundamental differences and design considerations for the selection of Optical Flame detectors - from the ISA Frequently Asked Questions about Flame Detection - A useful series of Questions and Answers related to types of Flame Detectors, location and installation, design and much more - from Desu Systems.

Visual Flame Detection - Optical flame detection has evolved over the last 30 years with improved sensors, processing power, and high electronics reliability, which has greatly improved the acceptance and use of automatic optical fire detection in the harshest of environments and applications.

Single wavelength ultraviolet UV detectors were originally used for the protection of large integrated oil and gas production platforms in the North Sea, followed by single wavelength infrared IR detectors, but problems with false alarms from numerous natural and artificial sources both on the platforms and from adjacent installations prompted the oil industry to search for a better technology. This paper covers the recurring problem of flare reflections on offshore platforms and how the evolving technology of visual flame detection has solved this problem.

Ultrasonic Detection Overview - Ultrasonic acoustic gas leak detection technology functions through the constant monitoring of wide areas by advanced acoustic sensors specially tuned to process ultrasound emitted from pressurized gas leaks. This detection technology has several advantages a It does not have to wait until a gas concentration has accumulated to potentially dangerous concentrations and b It does not require a gas cloud to eventually make physical contact with a sensor, and the response is instantaneous for all gas types - from Emerson Process Management.

This paper lists the main world-area standards to which protection types are tested and certified. In those countries mostly in Europe that have adopted the IEC standards. The IEC Series contains not only the hazardous locations requirements but also the gas detection performance requirements for both point and open path combustible gas detectors.

In offshore toxic gas applications, the ISA standard is generally the defacto global standard for most world areas. Gas detectors are a critical part of the overall safety system. Therefore, all standards require the gas detector, the controller, and the output for the performance approval. Output is often the annunciation device. This latest achievement underlines the position of CompEx as by far the world's most important international 'Ex' personnel certification scheme recognising core competency for safe working in potentially hazardous flammable or explosive atmospheres.

Since it was introduced in the s, CompEx has grown strongly every year due to the unique characteristics of the scheme:. Find more information here. Standard Update! The Value of Displacer Switch Technology for Level Detection in a Condensate Drip Leg - Displacer switch technology can provide highly accurate level detection for many applications in the power generation industry, including the steam generation process.

However, detecting level within the condensate drip leg or drip trap of a main steam line is a very challenging task for many power companies. To accurately measure this very difficult application, you need to implement highly reliable level instrumentation, but only a few manufacturers today are able to provide the technology that this process requires. To find the right solution for your facility, it is important to understand how displacement type liquid level technology functions within the condensate drip traps of a steam boiler.

Using Displacer Switch Technology to Control Sump Liquid Level - Displacer switch technology is a popular level control solution across numerous process industries today. This is particularly true for sump level control, where displacer switches can provide a low cost, automated solution that is highly reliable because it is not affected by surface turbulence, foam or changes in specific gravity.

This post discusses the use of displacer switch technology to automatically control level and provide overfill protection — or a high-level alarm — in a sump. Displacer Switch Technology Offers a Proven Solution for Liquid Level Measurement - Displacer switch technology provides accurate level measurement across all process industries today. To determine if this is the right solution for your facility, it is important to learn about displacement type liquid level measurement — and how this technology functions within industrial applications.

In fact, they are especially well suited to two particular applications — level control at nuclear facilities and interface service. Displacer Level Transmitter Technology Provides More Reliable Level Measurement than Torque Tubes - Many instrumentation and control managers have adopted torque tube technology for use in liquid applications. However, professionals across many processing industries — including chemical, petroleum refining, power generation, pulp and paper, nuclear power, crude oil processing and natural gas processing — have come to realize that range spring technology is a more reliable level measurement and control solution than torque tubes due to the output stability, structural integrity and ease of use it provides.

The comparison detailed in this post demonstrates the benefits that range spring technology may provide compared to torque tubes. This comparison uses a linear variable differential transformer LVDT transmitter with range spring technology. Application Considerations When Specifying Displacer Level Transmitter Technology for Liquid Measurement and Control - Displacer level transmitter technology plays a key role in the safe and effective measurement of liquids across all process industries.

This post discusses industrial level applications for displacer transmitter technology. Rupture Disk Preliminary Sizing for Atmospheric Venting - Preliminary sizing for rupture disks on liquid or gas service venting to atmospheric pressure. Imperial English units only - from www. Select the Right Process Safety System - Keeping Several "Do's and Don'ts" in Mind can Help - Paul Gruhn - Changes in technology have led to a variety of recent developments in process safety, with many suppliers releasing new systems that significantly depart from those traditionally available.

So, choosing a safety instrumented system SIS may seem even more complicated now. However, paying attention to a few do's and don'ts can make picking the right system for your process easier - from Chemical Processing and Rockwell. Summers - Safety and productivity at process plants suffer because too many engineers believe myths concerning design, implementation and operation of safety instrumented systems SISs. King - Many plants rely on safety instrumented systems SIS to address hazards. Determining whether such instrumented protection is needed and, if so, the appropriate Safety Integrity Level SIL is crucial for achieving the required level of safety.

A wide variety of methods are available for SIL determination. These are found within the "informative" sections of the standards and therefore aren't mandatory — you may choose one of those methods or a suitable alternative approach from elsewhere. However, certain issues and problems are common to the application of all methods. When considering safety in the process industry, there are several relevant national, industry, and company safety standards used when determining and applying safety within a process plant - from the ISA and InTech Have you considered Joining the ISA? It is well worth the minimal cost.

Process Safety Management Guidelines for Compliance - The major objective of process safety management PSM of highly hazardous chemicals is to prevent unwanted releases of hazardous chemicals especially into locations that could expose employees and others to serious hazards.

An effective process safety management program requires a systematic approach to evaluating the whole chemical process. Using this approach, the process design, process technology, process changes, operational and maintenance activities and procedures, non routine activities and procedures, emergency preparedness plans and procedures, training programs, and other elements that affect the process are all considered in the evaluation - This is an excellent document from the US Department of Labour. The MI section requires the inspection and testing of safety systems according to recognized and generally accepted good engineering practices, maintenance of testing records, and documented correction of any identified deficiencies - from the ISA.

Cybersecurity Matters, But How Much? During an aside at a conference I attended about a year ago, a representative for a major control systems provider told me that most of their large customers were facing attempted cyber attacks on a regular basis. Prior to this chat session, I had read a number of reports about cyber threats to industry, but it was difficult to quantify how pressing the concern was, as most industrial end-users, for obvious reasons, were pretty hush about the cyber threats they faced.

That said, information continues to emerge showing cybersecurity is a growing and very real concern for industry - from Flow Control.

Instrumentation Industry Standards — Whilst focused on Delta V This very useful resource from Emerson Process Management has a list of standards along with details such as a glossary of standards industry terminology, a directory of abbreviations often used in the instrumentation industry, and a primer on using electrical equipment in potentially explosive atmospheres.

The early problem of plants having to grapple with many different communicators was solved already in the mid nineties by standard protocols like HART and Foundation fieldbus together with the Electronic Device Description Language EDDL, formerly just known as DDL , an integral part of both technologies. A single universal field communicator supports all instruments, an arsenal of many communicators is no longer required.

Although many maintenance tasks can be done remotely from centrally located device management software part of Asset Management Solution AMS , there are several other tasks that must still be carried out in the field right next to the device. Because of such field work, a compact field communicator is highly valued by maintenance technicians.

A notebook computer is not ideal. EDDL is the only technology suitable for portable communicators because it works on embedded operating system used in such devices. IEC graphical enhancements the EDDL now make field communicators easier to use and powerful enough for complex devices. Intelligent Device Management Tutorial: Calibration - In the early days of smart transmitters the concept of remote range setting "remote calibration" and re-ranging without applying input was revolutionary. It took years of education to be accepted and understood.

Calibration can be carried out using a handheld communicator in the field, a laptop in the workshop, or from intelligent device management software as part of an asset management solution.
